Yep sounds like a UTI. There are over the counter tests you can buy to be sure... and then call your MD and tell them... you won't even have to go in probably.

I can't take the meds for that (and have to be really careful during swim suit time, and with some of these "modern" slenderizing clothing that have no cotton crotches! (TMI) ) so I use CHICKWEED tea to counter any UTI.

I don't know your age, but it can also develop from having too much sex!

You do have to do something about it quickly... and gain relief from that pain too!
