Looking for a hand doctor that can tell me what a problem might be...
I discovered something in my left hand last night. A little disturbing.
On my index finger, immediately under the first line at the end of the the palm, aproximately in the center of the width of the finger..is a "thing"

A nodule...or something...about the size of a B.B perhaps. If I flex my finger, it moves a bit. Part of a tendon, maybe? I can feel it roll around it I mess with it.
It is slighty painful, but only if pressure is applied to it..which is frequent, since I play guitar....although not frequently.
Could this be the beginning of tendonitis or something bad?
