Thumb shakes when I bend it at 90 degree angle

[dannydd]

As I was typing on my computer I noticed that my right thumb was shaking and it got me worried.  It only shakes if I bend it at a 90degree angle but it is still very worrisome.  About 3 hours ago I did scrub the bathtub and I thought that might have something to do with it but it has not stopped shaking in 3 hours.

Thanks,
Danny

Hi,
It could be Carpal tunnel syndrome . The median nerve provides sensation to the palm side of the thumb, index, middle fingers, as well as the inside half of the ring finger and muscle power to the thumb. When this nerve becomes pinched, numbness, tingling and sometimes pain of the affected fingers and hand may occur and radiate into the forearm. excessive repetitive movements of the arms, wrists or hands can aggravate the carpal tunnel bringing out the symptoms of carpal tunnel syndrome. Untreated, this can become chronic, but when detected early, carpal tunnel syndrome can be treated and recovery is possible in a few months. Please consult a neurologist and an orthopaedic surgeon for the diagnosis and treatment . Hope this helps you . Take care and regards !

I used to have this happen to me on several occasion at the beginning to the year, but after a few days it just sort of... stopped. Been reading a lot ever since because I fear it might come back. I do spend a lot of the time at my lap top, so I believe it has something to do with carpal tunnel, as I've red in this article https://helpyourback.org/health/why-your-thumb-keeps-twitching-involuntarily/

I have something similar and I was tested negative for carpal tunnel. Similar to yours, mine began after intense physical use when I was learning guitar and gripping it too tightly. It's been 3 years now and it still trembled when I bend it or do precise movements like texting. My doctor said it is not Parkinson's but she couldn't give any explanations. I wonder if a muscle knotted up at the base of the thumb and just needs to be released. Any insight would be appreciated.
