Yes! There are several things you can do to relieve your symptoms:
Keep the affected area as dry as possible and wear no underwear (if possible) to let the air get at the area. The dryer that you keep the area the faster it will heal. When coming out of the shower use your hair dryer on a lower setting to dry the area so that way you do not have to rub it with a towel. Apply cornstarch by sprinkling it on to the affected area as cornstarch helps to keep the area dry.
To decrease the itching at night take Benadryl before bed time.
To make you feel better as well bath in either Aveeno or Epsom salts. Also look for Dermoplast spray (the blue can for the genital area, not the red can) or another topical anesthetic spray - ask your pharmacist.
Whatever you do, don't scratch!!
The answer to your question would be to wait. As the itching will pass if it is Herpes with the use of Famciclovir.
You can ask your doctor for some kind of corticosteroid cream, however it is not recommended to apply it during treatment, but in cases of extreme itching it could be possible.
