I Am On A C Diff Antibiotic To Take Away

I am on a c diff antibiotic to take away the infection in fact it is my second batch of this med since it had come back a second time since my colon surgery, plus I am also noticing red bumps in couple differnt areas of my body like my left hand where I think an IV was but also on my left leg,left wrist and now right left side of knee, are these all side effects or is it something more in your opinion? I left out an important item, my ankles are swelling as well
