See your doctor. Are you running fever? Could be a sign of diabetes or prostate problems too.

no fever
I'm not running anykind of fever as far as i'm concerned but my lower part of my back has seriously been bothering me for the since about a week before my last period which was on the 16th march..

Certainly sounds like a UTI, but like I said see your doctor, they can be difficult to get ridd of. Also could be a sign of some STD's. hate to mention that. You really should see your doctor, more like your gyno, but someone. If it were the later it can cause birth defects and permanant dammage to you left untreated. Get checked out.

Yeah, you really need to see your healthcare provider. I agree that you likely have a UTI, of whatever cause. What concerns me is that you're having some back pain. It might be indicative of a kidney infection...rather then just in the bladder ie. Pyelonephritis.

Urinary Tract Infection help me please
Yes, definitely see your MD! The fact that you're having pain in your back may indicate that the infection has spread up in to your kidneys. Only antibiotics will help that. But while you're waiting to get in to the office, drink Cranberry juice. 8oz per day. Also drink 8 8oz glasses of WATER. This will help to flush out your system.
