After 7 days of taking clindomycin, after surgery, I broke out in a rash. It was very red, covered about 25% of my body, and was intensely itch. After consultation with my primary doc we think I should get tested. She would also like me to be tested for penicillin. Does anyone if these drugs can be tested for? I tried calling the allergist but it's hard to get thru and even harder to get a call back.
