My girlfriends vagina has had a really bad stench and it wont go away, yeast infection?

No. No, yeast infection by itself is not associated with foul odor. She needs to see her gyn to rule out other infections.

I was wondering does the white stuff in my vagina go away with prescribed meds for a yeast infection?

If white d/c is due. To yeast infection than proper treatment may resolve it. However, there can also be white discharge that is normal (leukorrhea). Symptoms of a yeast infection may include: burning, redness & itching of the vulva; burning with urination & vaginal intercourse & a clumpy, white, vaginal discharge with no odor.

So I thought I had a yeast infection but anything I put near my vagina just burns it really badly. I can't get sleep because I'm in so much pain.

See doctor. Go to see doctor now or if you cannot get in go to urgent care. You need not suffer like this now go.
GYN exam. This may be a complex infection requiring examination, culture, oral and topical antibiotics, I suggest that with such intense pain, that you go to the ER or UC clinic nearest your home, ASAP!

I'm 43 years old and never had a yeast infection or any problems in my vagina, but the last 2 weeks I've had a bad odor inside my vagina. There's no?

BV. This sounds like bacterial vaginosis. You need a pelvic exam to be sure and if it is BV you will need antibiotics to cure the infection.
Yeast infection. Sorry you had a bad odor. You must see your Gynecologist as soon as you can. Hope all goes well!
