I have been having really bad headaches with blurry vision and seeing colors that last 30 min to an hour, for 3 weeks now , and a sharp pain in my back right below my shoulder blade in my rids sort of and it lasts 2-3 hours if not longer,I'm 38 weeks pregnant on Friday by the way,I haven't had any protein in my urine or I don't think so the Dr. Hasn't said anything about it,and I haven't had any high blood pressure so I'm lost I went to the Dr. Today for the headaches because I had one that make me cry it hurt so bad and it frustrated me from having trouble seeing with the colors,she gave my a prescription for Tylenol with some pain killer mixed with it I don't recall the name and also told me when I got my next check-up to let her know if they haven't gotten better but I'm just curious for some ones opinion on my situation..
