Fingertip tingling, pain, and pressure-induced itchiness
Hello, my symptoms started a few months ago with sporadic tingling, pain, and pressure-induced itchiness in the tip of my index finger of my non-dominant (left) hand. There was also a slight red discoloration under the skin on the side of the fingertip. The symptoms worsened when I used my hand normally, so I tried using my right hand only. Gradually, these symptoms disappeared. Then I had pain in the wrist, thumb, and area between my index finger and thumb of the same hand. Again, I tried using my right hand only, and those symptoms gradually disappeared. Now the same fingertip is affected with my previous symptoms of tingling, pain, pressure-induced itchiness, and slight discoloration. Any ideas? Thanks!
'Abnormal nerve sensations such as pins-and-needles, tingling, burning, prickling or similar feelings are all known as "paresthesias". Some cases are severe enough to be considered painful.
Paresthesias usually result from nerve damage due to pressure, entrapment, or nerve diseases. Continued nerve damage can lead to finger numbness and permanent loss of feeling. Any abnormal sensation needs medical investigation.
Distinction as to which fingers are tingling is important to diagnosis. The main fingers are more likely to be affected by conditions such as carpal tunnel syndrome. The 4th and 5th fingers are affected by the ulnar nerve, which can be interrupted by pressure at the elbow or the chest area (e.g. thoracid outlet syndrome).
Parethesias in the hands and fingers can also be caused by broader diseases such as peripheral neuropathy (more common in the feet but hands can be affected) and various others. Correct diagnosis of the causes of finger paresthesias is important and treatment can often reverse the damage. '
