Hi I have recently been on two sets of Augmentin antibiotics for a chest infection I never responded so I then took Klacid, I got better quite quickly thereafter, I then got joint pain in my right wrist, that went away and then I got Joint pain in my left ankel the following day, I have been getting a rash on my neck which was like welts and then I used a cortisone cream and took antihestamine, this all went away but I keep getting different kinds of rashes and very dark rings under my eyes do you have any idea what could be wrong with me?
