Low oxalate diet & antihistamine

Has anyone had success with a low oxalate diet? I think this might be part of my problem as I have had a little bit of success w/ vitamin b6 reducing my burning pain. I don't have much time to write tonight but wanted to see if there was anyone on here who could share more?

I have also been taking Zyrtec which is an antihistamine normally used for allergies. I think it's been keeping things at a dull burning level (vs painful), but I am too nervous to stop them to see what I would be like without them! Anyone successfully using an antihistamine?

If an antihistamine is causing you to feel better you probably have an allergy to some thing. So eliminate stuff that comes in contact with your vagina...

My story is long, but here is the gist of it...My problems started with what we thought was a yeast infection, but the swelling and inflammation would not go away. I was given a antifungal cream that I had an allergic reaction to. I got the initial reaction from the cream calmed down and the swelling finally went away, but I have been left with a raw/irritated/hypersensitive spot around one of my bartholins gland. I had a biopsy a couple weeks ago and was told I had a cyst on the gland (it was removed). The area of skin where the cyst was removed no longer hurts, but I still have inflammation all around it and sometimes in the opening (1st inch) if my vagina. The Zyrtec seems to help the vaginal inflammation but not the inflammation around the gland area. Dr thinks since there are no noticeable causes of my remaining inflammation (that she has found) that my nerves are continuing to fire even though the infection is cleared up causing my body to produce an inflammatory response (producing histamines).

She has prescribed me a compounded cream (lidocaine & gabapentin) but I am still waiting to get it. The thought is the gabapentin will reduce the nerve response and stop the inflammation cycle. I am not sure I am totally bought into that theory. I am looking into the low oxalate diet and Dr Solomans Pain Project protocol. Google it - it's a pretty interesting theory! I have definitely noticed a correlation between what I eat and my pain level (tomato products and alcohol are completely off the table). I have been taking b6 and calcium citrate which help remove oxalates from your urine. The calcium didn't make much difference in my pain level (burning) but b6  makes a noticeable difference.  I am taking it 2-3 times a day.
