i have been experiencing terrible lower back pain for the past few years and no one can seem to figure out why. i am 21 yrs old and here is a breakdown of my medical history over the past few years...i have had frequent uti's (1 or more every 3 weeks or so) with no explanation. ive been to several urologists, all of which gave me the runaround. i have had a cat scan, vcug and blood taken and no abnormalities found. im on keflex right now, a daily antibiotic to suppress my infections, this is my second time trying this and its worked for about 3 months so far but i fear another infection could return just like it did the first time. i have a headache and am nauseated almost 100% of the day and i feel like this might be associated with my kidneys, back pain and urinary tract issues. i am so tired of this disruption and misery and i dont know what else to do since doctors arent seeming to help me. also, just in case they could in some way be connected, i was diagnosed with endometreosis when i was 14 years old. ive searched the internet and found a number of women with the same symptoms but no answers. if anyone can please help or give any sort of suggestions i would appreciate it more than you know. i really want to give up but my body wont let me because im constantly in pain. i know this is not normal and i am begging for help, please...
