I have been taking Metformin 500mg for about four months to lower my AlC. Since then, I have started noticing that my eyes ache, a sort of dry, painful ache. Now, I am experiencing constant pain/burning(?) in my vaginal area both inside and out. I have been prone to UTI's in the past, but always with different symptoms such as pain while urinating, fullness, and blood in my urine. This time is different, no blood, just constant pain. I went to my GYN yesterday and she did a urine culture and sent me for an internal pelvic ultrasound, both for which I am waiting the results. The ultrasound became extremely painful, I did not know if I would be able to handle her continuing. I am anxious to get my results, but can only wonder if taking Metformin has something to do with my symptoms since all of this started after I began taking it.
