question: My 18 yr old daughter has swollen fingers, has difficulty opening things like jars. In March she had developed a rash on her knees, elbows, backs of hands. It wasn t only a bumpy itchy rash, she also had flat purplish mottled areas also on her elbows and hands. The doctor said she had 2 things going on: a yeast infection and a rash. He was sure it was from the tanning beds ( yes teenagers, can t tell them anything ). The dr prescribed meds to stop the itch and kill the yeast infection. She was mostly cured but has been left with tender swollen fingers. Initial blood tests neg for mono, went back for more tests yesterday. Rheumatoid Arthritis??
