Help! I have pain and feel like I have a swollen vagina. I also have a rash/feel itchy on my inner thigh. What type of vaginitis do I have?

Hard to tell. You should see your doctor and have testing for STD's and vaginal infections so you can be treated correctly. Another possible cause is the latex in the condoms (assuming that you are using condoms). But first get checked for STD's ASAP!
