Pimple on labia. Needs treatment asap.

Hi, Since yesterday I was having itching near my urethra. As soon as I checked it, I saw pus filled little pimple on labia (maybe) (I don't know what frenulum-like thing over the urethra is called, having pimple exactly on it). 3-4 days back I got cough and high fever for which I didn't bath one of the days and wore a same underwear for 2 days straight (which was a little tight also). I'm not having pain in the pimple but sometimes it itches a lot, I don't do the itching but as soon as I wash the area with water, the itching goes away. I'm moving tomorrow morning to a different city, so will do a face to face visit there (as I don't wanna change my doc in case of some complication) but for now, I'm a little concerned if it's something major and needs treatment ASAP.
