I understand your concern.From the history i feel that you are having mild infection near the clitoral hood.
Like in penis the skin of clitoris
can be retracted pertly and impeded secretions can be removed if possible.That could be the reason for your pain.
I suggest you to try cleaning with any antiseptic like betadine
solution and apply an anti microbial ointment than hydrocortisone
If no relief may need to take antimicrobial tablets after getting a gynaec check up.
Hope my answer helps you.regards
