I cut my hand at work and now my thumb is numb. Do I have a nerve damage?

Possibly: Was the thumb numb immidiately after you cut it? Where on your thumb is it numb? Usually nerve damage causes only part of the thumb to be numb. For example a cut on the palm side of the thumb will make the tip of the thumb on one or both sides of the thumb feel numb but usually not the back of the thumb. If the whole thumb is numb it may be due to swelling. I would consult a hand surgeon. ...Read more

Nerve Damage (Definition)

A complete nerve transection will leave an area totally numb. The distribution of the numbers depends upon where the nerve was cut. A partial nerve injury may leave the area tingly or incompletely numb. Finally even if the nerve is not cut the swelling and bruising to the tea can affect the nerve as well. Usually we consider sharp penetrating injuries as likely having nerve lacerations when sensation is lost. A hand surgeon can examine the hand and pinpoint the site or extent of nerve injury and recommend ...Read more

I cut my thumb and now it's numb. I know I did some nerve damage and wanted to know if it will ever heal?

Hard to know: If just bruising of the nerve, it will heal. If completely divided, it may or may not heal and you could develop a painful neuroma at the injury site. If you need nerve repair, it is best done within 3 weeks of the injury. See a hand surgeon! ...Read more

I had a spinal fusion years ago. Now I have pain and cannot grip with my right hand. I also get right side numbness. Could it be nerve damage?

I had a spinal fusion years ago. Now I have pain and cannot grip with my right hand. I also get right side numbness. Could it be nerve damage?

Grip weakness: If the fusion was done years ago, and everything was ok for a while, there is probable no damage... A new problem could be coming from the levels above- or below the past surgery area, so it would be best to go back to your surgeon, or find a new doctor if the past physician is not available. New images with possibly a ct or MRI might be needed to find the cause; maybe a neurologist needs to help. ...Read more

In: In all likelihood you do. The digital nerves run up the sides of the fingers and are closer to the skin than the digital arteries. So if you cut an artery you would have had to cut the nerve. My guess from your description is that the injury is on the side of the index finger next to the long finger or maybe in the webspace between the fingers.

Nerve repairs have the best results if they are done within 3 weeks of the injury. If you see a hand surgeon, he/she can easily diagnose whether you have cut a nerve. ...Read more

Nerves: Nerves can get pinched by sleeping in funny positions, and this can result in temporary (and sometimes longer-lasting) numbness and weakness. A google search for the term "saturday night palsy" will reveal a "textbook example" of a not-so-common, but very well-recognized, nerve compression syndrome (in this case, of the radial nerve). Also, one of the contributing factors of carpal tunnel syndrome (pinching of the median nerve) may be hand position during sleep.

Other things can also cause numbness of the hands. Determining the cause involves a careful physical examination (which most doctors should be able to perform, but many cannot or do not), and sometimes requires special tests (including electrodiagnostic testing -- see my health guide at the link below) which probably get done more often than necessary.

Left undiagnosed and untreated, hand numbness can get worse, can become associated with weakness, and eventually cause inability to use the hands.

Indications that a doctor is qualified to diagnose the causes of hand numbness include board certification (such as by the american board of psychiatry and neurology and the american board of electrodiagnostic medicine). It is also a good idea to ensure that the board certified physician is the one who actually performs the examination, rather than a physician extender (pa or other) who is merely supervised by the physician. A thorough examination for hand numbness includes checking the strength of the major movements at each joint in the affected limb (fingers, wrists, elbows, shoulders, in this case), checking sensation in the entire affected limb up to and including the neck, checking reflexes at several points (forearms and both sides of the elbows at least), and checking coordination. This should be in addition to a general examination of the other limbs and major organs.

My hands are numb, is it a good idea to go to the ER or should I wait until monday to see my usual doctor for potential hand nerve damage?

Your doctor unless..: Acute onset numbness never before present is associated with injury and should be evaluated and treated soon.
Worsening of chronic numbness to "complete" is unusual and related to having ignored the long-standing problem. The er is for emergencies; you should rest, elevate, and take antiinflammatory meds until you see your doctor. ...Read more

I think I have ulnar nerve damage! My pinky is numb and tingling and the side of my hand is numb. My ring finger feels heavy and weak. I put ice on b?

Ice on b?: Without knowing more information I cannot affirm whether your ulnar nerve is damaged. What is the mechanism of injury? How long have you been having the symptom? What makes it better or worse? Also, I am not sure what your question is. What do you mean when you write: "I put ice on b? " Please clarify. Best wishes. ...Read more

Slept on my arm on a flight 15 hours ago and the right two fingers and side of Palm on my right hand are still numb. Nerve damage or blood clot?

Nerve compression: Compressing the median nerve will cause this on the palm side, compressing the radial nerve will cause his on the back of the hand. It's doubtful there is significant damage. Give it is day or so, it should return to normal.

A blood clot often causes pain and swelling, it is rare for it to cause numbness. Blood clots also tend not to form in arms during sleep. ...Read more

I was using scissors to cut paper and suddenly I felt something almost pop near the top of my thumb. Now my thumb is numb. Is this just a nerve?

Proper digital nerve: Not sure about the "almost popping" thing, but forceful pressure on the proper digital nerve in the thumb can cause numbness the point of compression down. Recovery depends on the level of injury (axonotmesis, neurapraxia, neuronotmesis) The numbness may resolves in a couple of days or may require a year if the nerve has to re-sprout from the dorsal root ganglia in the neck ...Read more

Recently cut my hand and now left side of index finger is completely numb. It's been under a week. Will feeling ever come back? (really scared)

Possibly, slowly: It sounds like you cut your finger deep enough to nick a superficial (near skin surface) nerve fiber that control sensation. That would mean cut is specifically on left side of index finger and that the numbness travels distal to that point (toward it of finger). These peripheral nerves can regrow slowly (1mm/mo). Any hand injury could be serious. Would have it checked within 48 hours. ...Read more

When & for how long: Nerve compressions can occur after relatively short times (minutes to hours) depending on the degree of nerve compression. Such can lead to numbness, weakness, loss of function. Duration depends on multiple factors: type of compression, location of injury, nerve involved, other coexisting illnesses. Has this lasted more than 3 days & you're no better, get examined. ...Read more

I was cutting rubber matting and pulling hard with my hand and arm now my right index finger and thumb have been numb for 2 days I did not cut them?

Nerve: There may be a nerve that you pulled or stretched. This type of injury generally recovers as the nerve recovers. You should regain the sensation in your hand. It is important not to re injure the same area. See you doctor for an exam and recommendations for healing. ...Read more

I cut my thumb palm side at knuckle about a week ago and I cut a nerve, the wound is healing nicely but the left side is numb will the feeling comback?

Probably: After cutting a cutaneous nerve on a thumb or finger, sensation is usually disturbed for quite some time, even if the wound is healing well. In part, regeneration of nerve at finger/thumb can take months because of the distance from the spinal cord (can be as long as 1 inch per month which is 36 months if you're 6' tall. Regeneration can be much quicker too. All depends on nerve injury severity ...Read more

I cut the inside of my thumb deep and has been numb above the cut since it happened. Will the nerve repair itself?

I cut the inside of my thumb deep and has been numb above the cut since it happened. Will the nerve repair itself?

Prob will improve: Depends on the locations of the cut. If it was close to the tip of the finger, and wasn't severe enough to need stitches, everything should heal and the numbness should eventually get better. If it was close to the palm, it's possible that the numbness might not go away. It could take several months to see a difference. A nerve regrows about the thickness of your thumbnail every day. ...Read more

I've been writing with a pencil for the past 10 hours straight and now the tip of my right index finger is numb, could I have caused nerve damage?

Likely mild: You could have temporarily compressed a small digital nerve on the finger, or this could be a presentation of a carpal tunnel syndrome. This might well reverse over the next few days, but if more fingers get involved, or symptoms worsen, would be useful to have your doctor examine this. ...Read more
