Constant vaginal burning/vulvodynia

Hi all :) , Sorry there's a lot to read here so bear with !

 I first started having what can best be described as a burning feeling just inside my vaginal opening and the vestibule at 17. I don't remember any obvious trigger but in that year these things happened: - I became 'sexually active' (such a cringey phrase! ) and lost my virginity - I began the contraceptive pill (Yasmin I think? ) - Had thrush for the first time - Had cystitis/urine infection I don't know if any of those things or the combination of them could have contributed to the offset of vulvodynia. 

(If you aren't familiar with vulvodynia, it is a chronic burning feeling in or/and around the vulva and vagina with no infection or obvious cause present. It can be constant or triggered) One gyneacologist wasn't 100% sure that's what it was but my GP thinks it is. I think it is because it describes all my symptoms. Something must have disrupted my vagina because I was perfectly fine before. I didn't change my diet or start doing anything differently and any infections I had were treated and any irritation or pain had been cleared up which is why it is so strange. Now having a pain-free vagina that I used to take for granted seems a luxury! 

I am now 21 and have finally sought help after suffering in silence. I had got tested for every STD under the sun several times, had blood tests etc. Everything was fine. When the sexual health nurses and my G.P examined me they always thought everything looked normal and health except one time they said it looked a little red and 'angry' lol.

My G.P referred me to a gynecologist 4 months ago and she was also confused! I was prescribed Gabapentin but it did little or nothing to alleviate the pain. I took it for about 6 weeks but had to stop as it was giving me severe headaches and slightly blurred vision (it is a major drug used to treat epilepsy! ) I had been told that it was brilliant for some and didn't work so well for others. Am now awaiting my follow up appointment to see what other options I can try. I am waiting for my second gyno appt. Some days it is unbearable and other times it is just uncomfortable. It is rarely painless but being distracted helps.

Also, sex is sometimes bearable and other times out of the question. I have been with my boyfriend for nearly 2 years and he is very understanding. I fortunately do not have any other health conditions and am appreciative of the fact I am in good health when others suffer from way worse and more serious, life threatening conditions. I am finding it very debilitating and it is worrying that doctors seem to know little about it. It is just so confusing to sometimes be in such pain and not know the cause. I have tried many creams to no avail. Some days I just want to scream and cut the whole area off! Sometimes I feel quite depressed. Just wondered if anyone else has had a similar experience of vulvodynia or vaginal pain/irritation? Or any treatments you have tried that alleviated the soreness, even just a little. 

Things I do/have tried: - Cotton undies only, none at night - No tampons - No condoms - No shower products only aqueous cream - Canesten,Vagisil - Lidocaine - rePhresh - e45 - cetraben cream - sylk gel - baking soda bath (I read it somewhere?!) - I have even tried inserting yoghurt and garlic cloves (crazy or what?!..it didn't help..) I am quite desperate! Feel free to post any ideas or questions. I am happy to give anything a go!
