I have been in horrible pain in my right side for the last 2 weeks off and on. Also, it hurts when I go to the bathroom either way, urine or bm, but no blood. I think it has something to do with a UTI. I was hurting on my grandson's wedding day, Oct. 10, blown up, my whole body but have finally gotten that down. I had a 2nd bag of iron and about a week later a flu shot. I've had bad reactions to iron before, but never the flu shot but figured that must've been the case.
