. I am type 2 diabetic and gave my self a shot before bed. Woke up with a blister on my lower stomach right side. Felt it sore in the middle of night. Went in to urgent care and Docter lanced it. He burned my skin. Since than I have returned 3 times. It seemed to be healing but now it is purple around and cheesy looking in the middle. I have been swimming the last cole days.
Hi, Perhaps the skin there has got infected. Central yellowish looking floor and surrounding redness are signs of it. Uncontrolled diabetes predisposes to skin and soft tissue infections. I suggest you to use an OTC topical antibiotic, e.g., either Newsprint Ointment or Mupirocin 2% ointment, twice daily for a few days.  In addition, I suggest you to take an oral antibiotic e.g., either Amoxicillin or Cephalexin, thrice daily for a week.  Hope I have answered your query. Let me know if I can assist you further.
