Not sure if the Sulfasalazine would be the cause of the headache each person is diffrent, but I have no problems with it. And no problems with Tylenol.
You headache is most likly came on because of this stupid disease, stop trying to figure it out! And don't beat yourself up, it's not your fault!
I have tried it all for the last 12 years and nothing works. Only meds help out!
