I have been expiercing what seems to be a uti for for a long time on and off and recently I made an appointment with my doctor but I started to experience very severe burning sensation out of normal and it wasn't going away so I hoped in a bath and used some vagisil ph balance in hopes it would kinda help ease the pain but no luck. IM really annoyed with this pain and I have school tomorrow and I know I won't be able to focus while I'm enduring this annoying pain what can I do someone please help!!!!!
