Thank you for your reply. The original scab is now quite large and the size of a quarter and flat and the number of smaller scabs/sores has increased significantly and appear to be slowly spreading outwards and down my legs. I put an antibiotic cream on it today and the itchiness has increased. I will see a dermatologist tomorrow so hopefully he will have an idea of what it is.
Hello,
One of the possibilities for such sores is of boils. Boils are caused by infection of the hair follicle by staph aureus. Hair follicles that are blocked by greasy creams, petroleum jelly, or similar products are more vulnerable to infection. Bacterial skin infections can be spread by shared cosmetics or washcloths, close human contact, or by contact with pus from a boil or carbuncle. Treatment includes antibiotics and do not touch or pick them up. You can however apply topical antibiotic creams like Neosporin or Bcatroban.
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.
