One of the possibilities for your symptoms is foot blisters. When a foot is hot and sweaty, the sock sticks to the foot. The sock and foot then rub against each other and the inside of the shoe causing blisters to appear. Wear shoes that fit properly and keep feet as dry as possible. Wearing wet shoes, boots and socks will aggravate the problem. So change socks regularly and use foot powder to help keep your feet dry.

If still the lumps persist, then please get it evaluated from a dermatologist and get other possibilities of phytophotodermatitis, bullosa diabeticorum and porphyria cutanea tarda ruled out.

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.
