If this IS herpes (and I doubt it is causing all your problems if you do have it), your Valtrex dose is way too low.
The dose for an outbreak is Valacyclovir 500 mg orally twice a day for 3 days OR Valacyclovir 1 g orally once a day for 5 days.
For suppression, it's either 5oo mg or 1 gm orally once a day. Outside of studies, 250 mg is never used.
I'd also like to see the testing you had done, and what it said. Make sure it's an IgG test, and that it has a separate result for type 1 and type 2. I'd like to know what the number for it is, too - it will be like 4.5 or 8.7 or 14.6 or something.
When you have sex, is it painful inside or outside? If it's painful outside, look up vulvodynia.
Cetaway and Texa are antihistamines. Are they giving that to you thinking you have an allergy to something, or to help you sleep? It IS possible that an allergy is contributing to this. Make sure you are using scent and dye free everything - laundry detergent, toilet paper, body washes, wipes, dryer sheets - anything that you can think of that comes into contact with your genital area, make it scent and dye free. Wear 100% cotton underwear. Wear all white ones. Don't douche. Don't use harsh soaps - the vagina is like a self-cleaning oven anyway, and doesn't really need to be washed. You can use a washcloth externally, but you don't need to do anything internally, or need soaps/washes externally. If you must use soap, use something very gentle, like Ivory or something for sensitive skin, with no scents or dyes.
If you were tested properly, and do have herpes, you may want to talk to your doctor about suppressive therapy. This is Valtrex taken every day to help prevent outbreaks. With everything else going on, the last thing you need is an outbreak.
Hi firstly tell us what test you had confirming positive for hsv2 as your symptoms dont appear as herpes.
