I was just diagnosed with ulcerstive colitis in January. I was put on sulfasalazine 500mg twice a day. I'm a little over a month in but ive been expierencing daily headaches for a few weeks. Its pressure more then a ache along with just heavy head feeling and slight lightheadedness. Its driving me nuts! Has anyone expierenced this or should i consult my Dr? Other then this pressure I really don't have any other issues. Thank you in advance!
