Welcome to ehealthforum.
Given your current symptoms (swollen and achy vagina, pain on intercourse suggests a local infection which is called a 'vaginitis'.
I recommend you to get examined by your healthcare provider, and get a possible vaginal swab done o look for the cause of the infection.
â¢Meanwhile you can do sitz bath with Savlon or Betadine solution.
â¢Keep the area dry and clean.
â¢Avoid having intercourse until you find out the cause and get treated.
â¢Both you and your husband should get treated simultaneously to avoid reinfection. Use barrier contraception (condoms) while you are on treatment.
Hope this helps.
Take care.
