I have been experiencing vaginal swelling, burning and redness for 2 weeks. Ive also noticed some white discharge and white residue Around my labia. This has also been accompanied by A large, swollen bump on the top of my rectum. It burns when I urinate and deficate, both my vaginal (labia) and anal areas are red. I also had sore throat with these symptoms. My primary physician prescribed azithromycin 250 mg dose pack, which cured the sore throat, but not the genital issues. I m worried it might be an STD. Do you have any advice? I m trying not to panic.
