I am having a continuous lower back pain on the left side of my body from past 3 days. the pain was severe one the first day but i took a sumo (painkiller) and the intensity of pain has reduced since then. I have also noticed that i go to toilet at least 8-9 times a day. I also feel little pain after i urinate, in my vagina. I searched about it on the internet and found symptoms similar to UTI. I need assistance as to which kind of doctor should i meet (gynecologist or physician).
