Hi mam usually if sugar levels are uncontrolled this type of problem occurs so it's not better to pick the wound by yourself. Just control the sugar levels and consult the planetologist and check for sugar levels and then go for Chat Doctor.  If you pick yourself it may lead to infection and may lead various typical severe problems. Thank you.
