I find monostat works well. A pharmacist can help you pick out the best one for you.
The pain has been goin down and I'm not peeing as much as before... But wat meds should I use to cure the yeast infection??
When I had a yeast infection I felt better after the second day of a 3 day treatment. There are also 5 day treatments, which work the same way and may be cheaper. If you're sure it's a yeast infection, use one of those treatments. I wasn't sexually active the last time I had a yeast infection so I don't know how soon you can go back to sex. But I think you would be safe as soon as your done with treatment.
If you keep getting repeated infections you should talk to your partner about cleanliness. If he has bad hygiene, it can easily give you infections. Repeats can also be a sign of a struggling immune system so if it doesn't go away with the treatment be sure to see a Dr.
How long does it take for a test infection to go away and wen will I be able to have sex again??
Swelling and painful itching can be a sign of a yeast infection. Frequent urination with pain could be a bladder infection. The rash later that day could have been an allergic reaction caused by lubricants (even water based can give people an allergic reaction) or condoms (although it doesn't sound like you used one?). There are even odd cases of women being allergic to a man's sperm. If your partner has a sexual history or any known STDs or STD symptoms you should probably get checked. Also there is no need panic about STD's most people at one time or another get one and most of them are curable. (Of course that's easier said than done and waiting for results caused me to bite off all my nails, so who am I to talk about not panicking?)
I'd suggest seeing a doctor. If it's not getting better, something needs to be done. Also until you know if it's an bladder or yeast infection its a good idea not to have sex, even if sex isn't painful it could be doing more damage if it is an infection. Also if your partner isn't careful it is possible for him to get an infection under his foreskin from you. So waiting on sex until it clears can be a good thing.
