Blusters on inner wall. Hi,

Hi, Thanks for helping me out and please suggest whom should I consult. I am suffering from some kind of infection on my vagina walls. I think it is at Vestibule and vaginal onfice. There was some irritation, itching and pain in initial days when it started. Now it's been 2 weeks, I am still having same issue while touching. [I have clicked few photos and seems like a trail of blisters on wall (not sure)]. In this 2 week time I had my periods but it went smoothly with some itching on the effected area. Recently I observed that this thing is not going away and I am worried. So please suggest me a solution or which doctor I should consult. It you know the name and treatment of this problem then please suggest me a solution. I am not is condition to visit any doctor soon so please suggest me something so I can get this thing away from me. Thanks again for reading this and suggestions. P.s.- I had rough sex before this thing started.
