My story, do you think it's vulvodynia?

First of all, I'm new. Hi
I'm not quite sure what is wrong with me and my first internet community posting really didn't yield many answers so I thought I'd try this forum. I feel like every one here is pretty knowledgeable and might be able to offer some good thoughts.

On December 16th I went home early from work because I had really uncomfortable vulva burning.
I'm pretty sure I kind of experienced this when I was around 15 (my memory is horrible), which is when I first found the term vulvodynia on the internet. But it happened maybe once a week, never for more than an hour and after a couple useless visits to the doctor, it kind of just went away and hasn't really affected me much in life. & the very few times it has since then, it has been the same-going away very quickly that I don't even really remember.
I do know that it was the worst it had ever been, but I expected to go home and have it go away. It never did! I have not been 100% since then.
I've been to two doctor visits. After a week of pain I went and was told that there seemed to be nothing wrong with me, but he sent out some cultures & prescribed me lotrisone. Almost three weeks later, I was back at the doctors not feeling any better. He told me there seemed to now be white blood cells/blood in the my urine, though I still physically looked fine. I left with prescriptions for Microbid (just finished last night), Phenazopyrid (though I have NO burning while urinating) and betamethasone dipropionate cream.

I'm still about the same. Besides the medicines I briefly tried a blander diet (low oxalate kind of), going without underwear at night, washing underwear in just hot water, applying vaseline...
I do have the feeling of ALWAYS having to urinate. Even after I have just went. It doesn't burn when I go, and I don't have any trouble with that. I have noticed that it hurts more after I use the bathroom, and I've realised it is somewhat because of wiping. I've started spraying myself with water and then gently patting myself dry. Which I totally don't feel clean enough after doing, but I guess it is better then badly burning.
I feel like my urethra is burny feeling, and I don't know if that is spreading to my vulva or vice versa.
Not wiping has helped the vulva burning feeling, I don't feel like crying from the pain as much but it has not completely stopped and then just feeling my urethra burning is uncomfortable.
My vagina basically feels fine, I had no problems with tampons during my period. If I press a finger on my vulva, it burns a little but it goes away quickly and really doesn't leave me in pain.
I think that is about all I have to say!

Any suggestions? I'm going to call the doctor's office tomorrow if I get the chance to check up on my urinalysis, and I have an appointment on the 6th of February where I am going to just confuse him more! I also don't have insurance so I am limited to who I can see, and I really can't afford many more visits.

Thank you for any suggestions!

Whenever I use the bathroom I fill a spray bottle with cold water and after im done peeing I pour the water over my vulvar lips and vaginal opening. I cup my left hand over it with my fingers gently touching the urethra and behind the vaginal opening. I can't stand wiping myself, I feel raw after and it wont go away and I just feel miserable. Another thing that might help is a frozen gelpack. You can buy them at a pharmacy or grocery store. You refreeze them after they defrost. I place 2 papertowels around it. I squeeze it into the shape I need it to be in and I spread my vulvar lips and press it against my urethra and v opening. I keep it there for maybe 10min and then very slowly pull it off. If you don't want to try a frozen gelpack then after the cold water rinse use a fan. Lay on your bed with a fan between your legs. I hope my advice has been helpful. These are some things I do on a daily basis for releif.
