I'm a newbie and really need some advice. Several months ago I felt a pain on the pad of my middle finger. I thought it might be a splinter, but could not find one. Since then it has become numb with a throbbing just under the skin. I have to wear a bandage all the time as the skin surface has become extremely sensitive. There is no swelling, in fact my finger tip seems to have decreased and the pad has a molted appearance. My family doctor nor my rheumatologist have not been able give a diagnosis. Í have had an x-ray and an ultrasound.
