I'm 30 years of age and was just to the doctor (MD Internal Medicine) with symptoms of a bladder infection (painful urination, frequent urges, chills) which I'm familiar with, only this time I had some spotting and very bad lower back pains, and a possible fever the one day, but none since...thus the reason I went to the doctor. Like an idiot I took 2 tylenol before going to the doctor, so I was feeling better while I was there. I was given a urine test, but at that time I didn't pass any blood. I was prescribed Cipro 500mg for 7 days for a UTI/possible kidney infection. I'm now on my 5th day of meds...here's a quick breakdown. First day, minor spotting/minor pain...2nd day- excruciating lower back pains (hurt to sit, lay, stand...just couldn't get comfortable) and heavier spotting, no fever. The next 2 days the pains were basically gone, but heavy bleeding like a heavy menstrual cycle or worse for those two days still no fever. Today I thought it was gone, but some minor spotting at the end of urination. I called my doctor yesterday because seeing blood is making me very uneasy and scared...and she asked that I report in on how I'm feeling...but it was her day off, so I explained to the receptionist my symptoms and questions, she contacted the doctor's voice mail and she never returned my call....2nd day now and I've heard nothing. Don't want to see her again being treated this way....don't know what's wrong and I won't go to the hospital...I feel physically better now, just the bleeding is concerning me mostly because my last menstrual cycle was very late December, so I'm not due anytime soon. I'm wondering if this is normal with bladder or kidney infections, or if maybe this is a possible miscarriage that I was unaware of? Looking back now, I had extreme soreness and sensitivity in my breasts for a good 3 weeks which I don't get as a PMS symptom, but when my period arrived, I figured I wasn't. I am a smoker, and so many problems have similar symptoms, but I've never had back pains or bleeding....If you could put my mind at ease a bit with some answers I'd be ever so grateful. Thanks for your time.
