Remicade Ulcerative Colitis, Thoat, Infusions, Blood Vessel, Ankles

Well, I have had 4 infusions for Ulcerative Colitis. I have had several side effects but none that seem to serious....I don't think. Anyway, I keep having problems with my ankles after each infusion. Once they swelled up and a large red spot appeared and I was unable to walk on it for 24 hours then the swelling went down and a week late it happened to the other ankle. The next infusion a blood vessel in my ankle swelled so large I thought it would bust I elevated it and that helped. Then swelling went down after a few hours but the area turned black and blue and took a week to go away. Now I have a cough and sour throat..... so I really don't know. I go for my next infusion the end of Sept. We'll see what happens then.
