A member asked:

A few days ago my thumb and back of my left hand felt numb. when i make a fist it feels almost like that area is covered in a thicker skin than the rest of my hand. today brown wirey barbs appeared when i rubbed it. any idea what this could be?

Unusual: This is a rather unusual reaction unless there was a previous skin lesion from an insect bite, fungus patch or another type of patchy skin disorder. A dermatologist is best to evaluate you for any unusual skin lesion. If thumb or hand numbness persist a pinched nerve is a possible cause and a neurologist could be consulted for evaluation.
