About 2 weeks ago,I started getting a yellowish white vaginal discharge and an itching sensation. I figured it was a yeast infection, but I started getting these red bumps on my inner thighs and one on the outside of my vagina. None on the inside though. The bumbs started getting a swelling red ring around them and some began to puss. I am also feeling extreme pain and some swelling of my vagina during and after intercourse. I don't have any health insurance, so I'm having trouble being able to go to the doctor's. Should I be concerned? what could it be?
