Hello, Welcome, and thanks for sharing your concern I went through your query, blisters are superficial skin lesions due to infection or reduced vascularity of the skin, it is important to know the cause and this gives idea on treatment. 1 do you have associated symptoms like fever, any history of injury, or swelling throughout the limb 2 are they only on one side or both sides 3 do you have any other co morbid condition like diabetes or hypertension or renal defects. You will also need some investigations depending on the cause of your problem I hope my advice would have been useful, in decision making regarding your treatment, still if you have any clarifications or doubts feel free to contact back. Thanks.
