So i had a random blister on my leg i went to urgent care they said it wasnt infected it popped and the skin underneath of where the blister was is yellow and red? and i have a whole in my leg? what does this mean?? is that normal?

Blister: If the yellow and red area is small and redness is not spreading, gently wash the area, pat dry, apply an antibacterial ointment like bacitracin or Neosporin, cover with a sterile gauze held in place with paper tape. The hole will gradually scab and fill in. Keep it protected. If spreading redness,pain,swelling or pus formation have a physician examine and advise you.
