I am in the process of finding a new GI
Hey -
Not to be blunt, but if your GI wont sign off on the FMLA paper, I would find a new GI that will work with you. Fortunately/Unfortunately every time I had a flare up and it effected my work, my GI was more the accomedating and would sign my papers for me. I am not sure how sever your flare ups are, but I know that mine would send me to the hospital for a week at a time. One time I did not immediately end up in the hospital, but I would still end up in the ER, but not be admitted.
I hope this helps you, again sorry for being blunt.
