hello. i am a 49 year old woman. I have had a dull ache in my lower left back region for a few days now. when I woke up this morning I had an extreme pain in the same area, and it literally brought me tears instantly as well as taking my breath away. all day it has hurt as I went about my day, but cannot bend over or move to fast, I have been on and off my heat pad all afternoon. its not getting any better, its acutally getting worse. I have also drank two bottles of cranberry juice, because I know it has worked in the past for a uti or kidney stones. this time the juice is not working and I am taking pain meds every four hours and they are not even helping much. any advise for me?
