Finger tingling. What's going on?

First of all, we should pay attention to whether there are traumatic factors in the upper limbs. If there is trauma, we can take a film to check. See if there are any problems such as fractures caused by some ulnar nerve damage, or radial nerve damage. If there are no problems in this area, there are also some muscle strain caused by muscle strain, some physical activity for a long time, and then affect the nerve, as well as blood supply of blood vessels, showing numbness. If there is some pain and numbness, it may be carpal tunnel syndrome. It may be that there are some tendon adhesions around the wrist joint, and then there is stenosis showing compression of the nerve. This situation needs to be treated with some small knife. There are also some mental diseases that need to be diagnosed by psychology.
