Diagnosed with cellulitis. I took bactrim 5 1/2 days and then had allergic reaction - burning, needle like, numbing feelings, swelling. Also a few chills. I was told to take benadryl every 4-6hrs, pepcid twice a day. Saw dr. the next day. Was given clindamycin 150mg 4x day and took that for 2 1/2 days and was told to stop because I continued with bad reactions. I am afraid that the bacteria was not killed and will return. What do you all think? I am now allergic to bactrim, penicillin and possibly clindamycin, so are there any other antibiotics that can kill cellulitis should it return?
