I have little red bumps between my anus and vagina and also little bumps on the lips of my vagina. It burns when I urinate and it hurts to have a bowel movement. My doctor gave me macrobid but he never tested my urine and nobody looked at it? He went off what I told him. Nobody told me what it is. I've had this pain for five days now. Today is day 3 on medication and nothing has changed?

Depending, you will need to go back for a proper diagnosis from a DIFFERENT doctor. Finish the medication you were given and if it goes away, which it might take several days to do, than nothing else is need but if it doesn't than a second opinion is required.
