I have been on Doxy for three weeks now to treat a skin infection...

I took Omniceph for 2 days and began itching all over. My Dr. had me stop it but 2 days aftere stopping it my knee and wrist on the left side hurt and I couldn't pick anything up with my left hand. The weird thing is that one day it is my left hand and one day it will be my right hand. Today makes the 6th day I have been off of the drug and my right wrist is still aching so bad. It goes all up my fingers. Will this stop? I am really starting to get worried about it.

I have have fluttering sensations(palipitations) in my left upper back just behind the shoulder blade area? No pain just flutters? I'm 37 and you?

I had my second tablet today. I am experiencing pain in my heart, left hand and even on my left top of my head (back). Also experiencing chills once in a while. I am 34. I am taking Doxy for bacterial infection (UTI)
