go for a thorough examination...use augmentin ALONG with gentamicin if ur UTI has progressed,,,
You need to go to the doctor ASAP. You have all the symptoms of UTI, which left untreated may have developed into a bladder infection or kidney infection. I get them all the time and you have the classic symptoms. Especially if drinking a beer helped the pain as beer flushes your urinary tract.
There is usually no discharge, itching or anything like you would get if you had a yeast infection, and a UTI is SO easy to get from having sex. Especially if you didn't use the bathroom immediately after sex.
All you have to do at the doctor's office is pee in a cup, no exam neccessary, so don't hesitate or it will get worse. Sometimes you can keep it away with drinking a lot of water and cranberry juice but once it gets to the point of serious pain, you really need anti-biotics. Seriously, it's not worth it to wait it out.
