Thanks for the response. I called my Rheumatologist and it turns out that it was a combination of taking psudophedrine, having low blood sugar (from no appetite), and the position I was squatting in (raised my blood pressure too fast). I am glad it is not a reaction to the Sulfasalazine thus far, but I have only been taking it for a few days now. We will have to wait and see if the benefits outweight the side-effects for me. Thanks again....
