I have an infection on my lower legs I think that started from cat scratches about a year ago. Blisters appear then bust with liquid and crust over and the skin is red. I'm not diabetic and I'm about 60lbs overweight. I've seen a Dr before and was given a ointment that was something like Murpurcin or close to it and it seemed to help but I lost it and I'm tired of this but am not going to the Dr and would like to know if any of the antibiotics I have (I prep) on hand will work.. Keflex 500mgs, Bactrim DS, Levaquin 500mgs, Clindamycin, Amoxicillin 250mgs, a couple 1000mg Azithromycin, Omnicef 600mgs and some vials of Rocephin 2 grams each and a big bottle of Bicillin. My next buys are gonna be Doxy 100mgs, Cipro 500mgs and Flagyl 200mgs but I guess it was even pointless to say that lol. Thanks
