Hi,

I have this strange sensation on my outer labia. During the day when my pubic hair rub on my labia from the friction from walking it almost feels like a stabbing sensation. Is is uncomfortable. Also, in the same area, I experience burning after intercourse. Note, the burning is not in my vagina, it is on the outside, sometimes so bad that i have to apply a washcloth soaked in cold water to relieve the burning.
What could be causing this?
I am 41, have have 5 children and am in otherwise good health.
I would also like to add that i do not have a thick discharge. Thank you!
