Muscle Weakness (Definition)

Muscle weakness is either a subjective or objective symptom based on history or formalized testing. As a result, any complaint of weakness needs to be correlated with testing that can bring out that weakness, which sometimes involves putting that muscle in an isolated and 'disadvantaged' scenario to assess adequately. Such weakness can have multiple etiologies from ...Read more

Will muscle weakness from a pinched nerve reverse itself over time?

Will muscle weakness from a pinched nerve reverse itself over time?

Sometimes: It depends on the degree of the compression and the duration of the compression. Often when a nerve is first pinched, there will be a lot of pain associated with that. Then the pain is replaced by numbness. Even though the patient feels better with decreased pain, this means that the nerve is much sicker because it can no longer transmit signals. Relief of the compression at may or may not help.

I have a pinched nerve that has lead to muscle weakness/atrophy. Will I regain my strength and muscle mass?

I have a pinched nerve that has lead to muscle weakness/atrophy. Will I regain my strength and muscle mass?

Weakness & Atrophy: Significant weakness may be a sign of permanent nerve injury. Continued nerve pain with weakness would indicate an "active" nerve compression and a clear indication for surgery. Strength can improve but muscle atrophy may not change if the process is chronic, greater than 6 months.

Can a compressed nerve in the back cause you to have muscle weakness and wasting in your upper body and lower body. Arms and legs muscle.

Can a compressed nerve in the back cause you to have muscle weakness and wasting in your upper body and lower body. Arms and legs muscle.

Nerve Compression: Nerve compression can cause weakness and muscle wasting in the extremities. The nerves coming out of your neck go down the arm. The nerves coming out of the back go down your legs. If there is wasting in both the arms and the legs, their is likely a problem with both back and neck. See your chiropractor, for spine manipulation and rehabilitation.

What nerve causes facial muscle weakness?

What nerve causes facial muscle weakness?

Cranial Nerves: Facial expression and movement are controlled by several of the cranial nerves (cn). Ocular motion by cn3, 4, 6. Eyebrow lift by cn3, eyelid closing by cn7, muscles of chewing by cn5 and the rest of the face by cn7.

Can being bit by a tarantula cause muscle weakness or nerve pain?

Can being bit by a tarantula cause muscle weakness or nerve pain?

Depends of type: Of tarantula. Many species of tarantulas are not harmful to humans. If a tarantula bites it might be a “dry” bite – injecting little to no venom. However, the bite of some tarantulas can cause pain & swelling at the site, muscle cramping, fever, difficulty breathing and exhaustion. The Chinese Bird Spider (a type of tarantula) has been blamed for one death in China.

Can nerve entrapment cause weight loss, muscle wasting and muscle weakness.

Can nerve entrapment cause weight loss, muscle wasting and muscle weakness.

No and Yes: Motor nerve entrapment can definitely cause muscle wasting & weakness - but only of a particular muscle or muscle group innervated by that nerve. It's unlikely to cause weight loss except if you lose a large amount of muscle mass.If generalized weight loss &/or generalized muscle weakness is occurring, you need a proper medical evaluation to determine cause; it's unlikely to be nerve entrapment.

Can a lumbar puncture that caused explosive pain in the thigh cause nerve damage and muscle weakness in the same area? Is that damage permanent?

Can a lumbar puncture that caused explosive pain in the thigh cause nerve damage and muscle weakness in the same area? Is that damage permanent?

Could: Whether there is damage (let alone whether it is permanent) can be best determined by a good neurologic exam and may require an emg.

Can a pinched spinal cord in the neck cause muscle weakness and astrophy on your whole arm and leg muscle. Can a pinch back spinal cause same.

Can a pinched spinal cord in the neck cause muscle weakness and astrophy on your whole arm and leg muscle. Can a pinch back spinal cause same.

To involve the leg: There would have to be spinal cord involvement or a second lesion below the cervical level. If you develop increased tone and reflexes to go along with weakness and atrophy the problem may be further upstream (eg stroke). If the issue is "where is the lesion? " the answer may need to come from a neurologist. That's a big part of what we do.

Can an untreated swollen spinal cord cause same symptoms as multiple sclerosis and if so can the nerve damage and muscle weakness be made better?

Can an untreated swollen spinal cord cause same symptoms as multiple sclerosis and if so can the nerve damage and muscle weakness be made better?

Perhaps: Spinal cord swelling can be secondary to variety of causes, such as neuromyelitis optica, trauma, MS, tumors, and could cause localized symptoms indistinguishable from your MS. (Have you had an anti-aquaporin 4 test?) Typically might treat with steroids, but this would make your diabetes temporarily worse. Acthar might create a lesser complication. Check for NMO prior to starting MS med.

Does muscle weakness in children always have an underlining condition or cause?

Does muscle weakness in children always have an underlining condition or cause?

Usually: Children should not be displaying muscle weakness. There is often a cause. See a pediatric neurologist for the best diagnosis.

Why does hyperkalemia cause muscle weakness?

Why does hyperkalemia cause muscle weakness?

Dysfunction: It interferes with the muscles ability to contract because it alters the electrolyte balance across the muscle memberane. You have to have the right balance of potassium and other electrolytes for the contractile elements of the muscle to be able to contract which is what gives you movement and strength.

Does a elevated MCV cause muscle weakness.?

In short: The short answer is no. The elevated MCV needs to be looked at along other parameters of CBC and could reflect B12 deficiency or folate (folic acid) deficiency and mds.

Does hypo or hyperkalemia cause muscle weakness?

Does hypo or hyperkalemia cause muscle weakness?

Hypo: Potassium is needed to help muscle function. Without enough potassium, there is a change in the conduction of cells within a muscle. This change can lead to cramping, weakness and even heart arrythmias. People who have poor diets or who take diuretics "water pills" can develop hypokalemia more often.

What is something that could cause numbness and slight muscle weakness through my body?

What is something that could cause numbness and slight muscle weakness through my body?

So many things: There are so many things that could produce these very non specific symptoms. It really would not be responsible for me to list them here. It would be best to see your doctor and discuss your symptoms.

When a nerve in the face is damaged (not severed) does muscle weakness slowly get better or spontaneously work as the nerve heals?

When a nerve in the face is damaged (not severed) does muscle weakness slowly get better or spontaneously work as the nerve heals?

Expect this: If the nerve coverings are the source of damage, it will take about 4 weeks, but if the central axonal core is affected, recovery speed is similar to fingernail growth, about 0.1 mm per day. Your surgeon can help explain this process.

Why does hypokalemia cause muscle weakness?

Muscles need lytes: Your muscles and nerves require potassium to properly contract and relax. If low, they don't work as efficiently

What causes creatinine kinase levels to rise with muscle weakness?

What causes creatinine kinase levels to rise with muscle weakness?

Damage to muscle: The correct term is creatine kinase (ck). Creatinine is something else. Useful to know: most "muscle" weakness is actually caused by nerve, not muscle, malfunction. True muscle weakess: myocytes (muscle cells) contain lots of the enzyme ck. Low levels are found in blood normally. Damage to myocyte cell membranes from a variety of causes causes leakage of ck into the blood. Recovery->normalization.

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


Muscle (Definition)

It is a body tissue that has the ability to contract. It shortens and generates force. It relaxes and returns to its original length. Muscles move joints, stabilize the body, move air and food through the organs, act as valves for bladder, bowel and other organs. They control movement of the eyes. They help us express ourselves by changing the shape of our ...Read more
