Here I suggest checking the symptoms like pain along with swelling also. If its in combination then you need to check is there any discharge from the wound. All this in combination indicates towards infection. So you need to take antibiotic and once again consult the doctor for your would examination as well to check with blood test, sugar test and lab investigation if needed. Based on report he can help you with specific antibiotic also in a later stage. And Don't allow water to touch your leg especially at wound area. Take care.
