Hi,
To relieve pain, you must avoid all irritants, like underwear, tight clothes, pads, panty liners etc. You may also use Local
Xylocaine gel 2% to relieve pain. There are several causes for the sores. Management depends on the cause for the same.
If it is infected, you need some
local antibiotic Ointments, like
Tetracycline or Bactroban Oint. It could be
Herpes simplex , for which you need
Acyclovir Ointment as well as oral Acyclovir tablets.
HPV virus, is a sexually transmitted virus, though it has many strains, and few of them are high risk to develop cancer of the cervix. Others may disappear spontaneously. SO I would advice you to go for tests to know the type of HPV Strains.
I hope this will help you relieve your pain, and sore.
If you need specific treatment, may be you can provide more information like any other symptoms, Lymphnode enlargement, etc.
