This is totally a guess but I am wondering if you may be having a reaction to Remicade. I get occasional shortness of breath now I am on Humira and 6MP but I had tingling hands when I was starting to have reactions to Remicade and the puffy face and trouble breathing sounds like possibly a reaction.
