Nerve (Definition)

The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more

EMG/NCV says pinched nerve of L4, L5, S1, S2 (racepinephrine). I do not have weakness, atrophy, change in sensation, or any other complaint. Might be misdiagnosis?

EMG/NCV says pinched nerve of L4, L5, S1, S2 (racepinephrine). I do not have weakness, atrophy, change in sensation, or any other complaint. Might be misdiagnosis?

Yes: EMG is complex and the report requires interpretation. Sometimes muscle spasm in the back causes abnormality of the back muscles that is described as lumbar radiculopathy but may not be a significant pinched nerve.

Tests need to be taken in the context of the patient and their complaints and physical examination, just as you have suggested. ...Read more

Could a pinched nerve in L4, L5, S1, or S2 (racepinephrine) cause the right lower leg to look rounder than the other in the back of the leg but measure the same?

Could a pinched nerve in L4, L5, S1, or S2 (racepinephrine) cause the right lower leg to look rounder than the other in the back of the leg but measure the same?

R/O BAKERS CYST: Usually a pinched nerve in that region will cause sciatica and neuropathic pain. This may result in muscle atrophy and later potential foot drop. If the area behind the knee is full you may have a Bakers Cyst or potentially a DVT. An Doppler US or MRI IS NEEDED to define the anatomy. ...Read more

Can a pinched nerve of the L4, L5, S1, or S2 (racepinephrine) cause difficulty passing stool, i.e., rectum/sphincter won't relax/function properly?

? cauda equina syndr.: If you possess a large ruptured disk in the lower back which compresses multiple nerve roots, or if you have lumbar stenosis, this could affect both bowel and bladder, but a localized pinched nerve at the root level otherwise will have not influence on bowel dysfnctn. ...Read more

My emg shows pinched nerves in l5-s1 region but the MRI is negative. How is this possible?

My emg shows pinched nerves in l5-s1 region but the MRI is negative. How is this possible?

Complementary...: The MRI shows a picture of the vertebrae and discs, but it does not show how the nerves are functioning. The two tests are complementary: one shows structure and the other shows function. A pinched L5 or s1 nerve does not always mean it is trapped by a disc or bone spur-- it may get damaged or pinched intermittently when your spine moves, or may have incurred stretch damage. ...Read more

Have a bulging disc with nerve compression at L5/S1, what distance is safe for me to walk each with a 10kg backpack for me to have no pain. Thank u?

Have a bulging disc with nerve compression at L5/S1, what distance is safe for me to walk each with a 10kg backpack for me to have no pain. Thank u?

Get a lumbar pack: Be kind to your back and it will be kind to you.
Backpacks are hard on the low back. Large fanny packs are known as "lumbar waist packs" allowing one to carry a lot of the weight directly on the hips and decrease back strain. See: http://www. Ebay. Com/sch/i.html? _trksid=p5197.m570.l1313&_nkw=lumbar+fanny+pack&_sacat=0&_from=R40

I had a bone spur removed from my l5/s1 due to nerve compression. How likely are they to grow back?

I had a bone spur removed from my l5/s1 due to nerve compression. How likely are they to grow back?

Somewhat likely.: By bone spur, I assume you are referring to osteophytes caused by arthritis to the facet joints of the back.

Facet degeneration is a continous process, and over time, will cause increasing bone spurs.

Most of the time, we can accommodate these bone spurs, without surgery. In some instances, the bone spurs will cause enough nerve compression, causing severe pain, weakness and numbness. ...Read more

Have moderate /severe radiculopathy that started and progressed more than a year after L5/S1 ADR surgery. EMG showed compressed nerve. Causes for this?

Have moderate /severe radiculopathy that started and progressed more than a year after L5/S1 ADR surgery. EMG showed compressed nerve. Causes for this?

Postlaminectomy synd: Post Laminetomy syndrome can be flared following ADR surgery.The resulting nerve pain is due to altered kinetics, gravity or possibly scar. Other times the surgery just cant stop progression of disease and nerve damage. See your surgeon right away to evaluate: starting physical therapy focusing on core strengthening, postop imaging, epidural injection or SI joint examination or possible injection. ...Read more

L5-s1 disk herniated and cauda equina, did surgery 4 months before. My bladder not empties so urologist thinks still be nerve compression. Is that so?

L5-s1 disk herniated and cauda equina, did surgery 4 months before. My bladder not empties so urologist thinks still be nerve compression. Is that so?

Maybe, maybe not: Acute cauda equina syndrome from a ruptured disk in the low back is an urgent problem & is best treated with surgery. However, not everyone gets better. Residual numbness in the private area and difficulties with bladder emptying can remain despite surgery. It is something to discuss with your spine surgeon. She and he can assess, seeing if you need further tests like an mri. ...Read more

Difference between l5/s1 rhitozomy and nerve block?

Difference between l5/s1 rhitozomy and nerve block?

Length of relief: Nerve blocks use local anesthetic to "numb" the nerve so it does not transmit pain messages to the brain. Rhizotomy uses heat (or cold or a chemical) to inactivate the nerve. Blocks last hours, rhizotomy lasts months. ...Read more

What to do if I have pain around rectal area I was wondering if L5 s1 nerve's travel's to rectal area?

See your doctor for: An examination, lots of things can cause this. The rectal area involves the S1 to the S5. Much closer to your anus involves the S4 and S5 nerve. With the coccygeal nerve supplying sensation to the skin on top of the coccyx. Your symptoms maybe unrelated to your spine. If you have changes in your bowel/bladder function, or numbness over your anus/buttock area, then go seek care right away. ...Read more

I have an appt for an epidural for a nerve issue, near L5 s1 I think. What can I expect at & after the appt?

Maybe some discomfor: I might assume that you are going for epidural steroid injection, for a possible disc issue. This can work if inflammation is involved and is usually worth a shot. You might get some transient discomfort, but for the most part is benign and well tolerated. The important thing is to see if it help and call your doc if concerns arise. ...Read more

I was diagnosed with spondylosis l5/s1, which is now affecting my nerves I've been advised to have surgery but how bad can it get without surgery?

I was diagnosed with spondylosis l5/s1, which is now affecting my nerves I've been advised to have surgery but how bad can it get without surgery?

How bad is bad?: Surgery for your condition, or almost any other spinal condition is indicated by several things. First, intolerable pain (which is a subjective, non-measurable quality)
if pain is the only issue & you can adapt to it, don't do surgery
second, is functional loss which means impaired walking, severe leg weakness, bowel/bladder problems or severely restricted spinal mobility). ...Read more

What's " displacement of nerve root " for L5-S1 in my spine?

Roots: Can be displaced or compressed by pathology in and/or around the intervertebral foramina. L5/S1 root displacement can causes lower back, buttock, lateral thigh and anterolateral calf pain. It can also cause specific sensory and strength deficits along its distribution. ...Read more

L5-s1 shows annular tear and a central protrusion touching both s1 roots and thecal sac. No effacement or deformity. Nerve roots exit normally.

Your question is?: If the disc is worsening and causing weakness, muscular atrophy and/or numbness, and especially if initiation of urination is troublesome, need to have a spinal surgeon involved. Otherwise, conservative therapies may be successful. An EMG test may determine extent of nerve damage at this point and act as a baseline. ...Read more

In degen. Disc disease, is it better to fuse l5-s1 if disc 1/2 collapsed or wait til disc completely goes & pain is unbearable & nerve damage occurs?

In degen. Disc disease, is it better to fuse l5-s1 if disc 1/2 collapsed or wait til disc completely goes & pain is unbearable & nerve damage occurs?

None: Usually, degenerative disc disease is not surgically corrected if no nerve impingement is present. Just treating back pain with surgery will cause more back pain due to scarring and presence of the presence at other levels. If there is nerve impingement and symptoms of it, then surgery will help free the nerve and improve the symptoms. ...Read more

Interpret-please. Mild broad-based disc bulge L5-S1 may contact S1 nerve root emerging from dural sac. 2 nerve roots don't appear compressed.

Back pain: It means the person who got this done was complaining of back pain probably with some radiation down one of the legs or perhaps even both. Symptoms of numbness, tingling, or burning pain may also be part of this picture. The MRI report is suggesting there is a bulging disc, which is not a hernia, which may be causing irritation of nerve fibers while not physically squeezing them. ...Read more

I had a micro discectomy L5 s1 feb 15, no more electrocution, but still pain along the same sciatic line 2 months later? It's off the nerve.

I had a micro discectomy L5 s1 feb 15, no more electrocution, but still pain along the same sciatic line 2 months later? It's off the nerve.

Microdiscectomy: It is possible that a residual or recurrent disc herniation could cause persistent pain - an MRI with/without contrast would document this. Also, unfortunately there are also cases in which the nerve has already sustained permanent damage, so even if a microdiscectomy is technically successful and without complications, the nerve damage may not be reversible. ...Read more

S-1 Radiculopathy?: Real question here is the effect of the contact with the right s-1 nerve root, is there foot numbness or weakness, is there risk for future nerve damage into leg? An EMG can help objectify current integrity and/or future risk. Films do not necessarily advise surgery, and, the disc may dessicate over next 6-9 months and thereby shrink on its own, if you can be patient. ...Read more

How many corticosteroid nerve blockage injections can I have, for my sciatica and discopathy L5-S1 problem?

How many corticosteroid nerve blockage injections can I have, for my sciatica and discopathy L5-S1 problem?

3-4 injections: There are no limits to how many epidural injections you can have. That said repeated steroid based injections put your body at risk for other medical issues down the road. Good rule of thumb is no more than 3 injections in 6 months. If your pain persists after a good physical therapy trial, consider the injections. ...Read more

Can L5 s1 bulge with nerve impingement cause the bladder to not empty properly?

Can L5 s1 bulge with nerve impingement cause the bladder to not empty properly?

No.: Spinal nerves have myotomes, which innervate certain muscles, & dermatomes, which innervate certain areas of skin. The L5/S1 myatomes wiggle the toes/point the foot. The bladder is in the S4 myatome, which also controls the anus. ...Read more
