<s>[INST] I had shingles along my left leg following classic dermatome. Don t recall the name of the prescription I took, but it worked well. Recently I noticed a very small bump (~1/3 of a centimeter diam) between my left thumb and forefinger. Experienced several very brief instances of pain as though from a burn at that spot. -- Also occasional sharp pain as though from a splinter on the tip of my left ring finger. Could this be related? Almost 70. Female, 120 lbs, 5 3 [/INST] Hi and welcome to Healthcaremagic. I understand your concerns.It may be related and this may be recent shingles break up. It would be good if you do laboratory herpes testing to se if there are herpes antibodies present. If not, then some other causes may be considered and these include arhritis or hpv warts so xrays shold be done to see if sthere some chnages on small hand and finger joints. I am sure that this is something benign and will be easily treated.I hope I have answered you query.Kindly regards. Wish you a good health. </s>
