itching, and burning. What should i be doing?

Hi,
Welcome to ehealthforum,
Itching and burning in vagina could be suggestive of infection. Look out for any other symptoms like foul smell, altered discharge etc. Consider visiting your doctor/gynecologist for examination and vaginal swab/smear test to identify causative agent and get started on proper treatment as appropriate. Since you are sexually active, get your partner also treated simultaneously to prevent chances of re-infection. Drink plenty of water. Avoid vaginal douching, use of harsh soap or perfumes in the area (vagina has its own mechanism of cleaning itself. Use of these products harms the normal bacteria of vagina and it becomes susceptible to infection). Use loose cotton undergarments and avoid tight fitting clothes. Avoid having unprotected intercourse while both of you are on treatment course. If you intend to remain sexually active, consider visiting your gynecologist to get started on suitable regular birth control measures to be protected (after your periods). Be regular with birth control use as instructed. Avoid having unprotected sexual contact.
Take care.
