I have a 16 year old daughter. Her leg is bright red from the knee down on her right leg and only in the front. It was diagnosed as MRSA and then it was diagnosed as cellulitis. oh she has had this 5 times and been in the hospital all 5 times. Hospital sent us to infectious diseases. They said its not either of the 2 she was diagnosed with. So they sent us to dermatology. Dermatology did a biopsy first results they dont know they had to send it out to another lab. Havent gotten any results. she has a lot of pain in her knee and ankle. She has this for 16 days now and the doctors act like nothing is wrong. This is driving me crazy is anyone else have a problem like this?
