Hello, thanks for using HCM.
there are several causes of vulva
pain that include infectious, traumatic and allergic causes. Infectious causes include Candidiasis
and bartholin gland abscess
or cyst. The bartholin glands are located at the 4 and 8 o'clock positions with respect to the opening of the vagina and could become infected forming an abscess or become blocked to form a cyst. both conditions are associated with pain on the side and usually with swelling.
If the pains started before the headaches
and mood swings, it is likely that it is stress
as you worry about the pain that is the cause, if other wise other causes have to be investigated.
However, its only after a close look and examination that the diagnosis could be certain, so i will advice you see a Doctor and in the main time avoid wearing tight and non cotton under wears, and also avoid using irritative creams.
Best regards and hope this helps.
