Hello,
It can be due to pompholyx. Pompholyx primarily involves the hands and fingers and then may involve the feet. The first stage is acute and presents as itchy blisters on the hands, fingers and toes. Then the chronic stage shows more peeling, cracking, or crusting. Then the skin heals up, or the blistering may start again. The exact cause is not known and excessive sweating can be one of the reasons.
Please get an evaluation done from a dermatologist to confirm the diagnosis.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Sounds like a simple case of warts to me. I've had this before and they can be a pain in the *** to clear up. Squeezing and picking at them is the last thing you want to do as this causes the bacteria to spread and a whole new cluster to pop up. There are plenty of wart and bacterial-infection creams in drug stores (like "Wartner", availale at London Drugs, Shoppers, etc.) that can help. Washing your hands with an anti-bacterial soap is important in stopping the spreading.
