Thank you for clarifying,
I am sorry you are experiencing these symptoms.
The nerve that supplies your pinky finger (and also part of the ring finger) is the ulnar nerve.
This most commonly is compressed at the elbow. If you rest your elbow on a table when you are typing, this can lead to the compression.
It can also become entrapped at the collarbone level or the wrist level (from a cyst).
Using anti-inflammatories may be helpful along with an elbow pad (like rollerbladers use) or simply wrapping padding with an ACE bandage.
However, if you are constantly numb, these may not help much. The sooner you are able to have treatment, the better so that you do not lose muscle in the area that the nerve supplies.
An EMG/nerve conduction test will be able to tell where the nerve is being pinched.
