My Girlfriend And I Have Had A Lot Of Sex

My girlfriend and I have had A lot of sex over the last six months recently over the last 2 months her clit became overly stimulated, pins n needles and desensitized where it takes her about 10 times longer to orgasm from oral. She literally would orgasm in 2-3 minutes with oral sex and we now are assuming she has nerve damage to her clit. Her clit throbs when she gets aroused and hurts w pins n needles and now we are on a sexual hiatus to help her heal. Thoughts?
