Pain in mid to lower back as soon as I lay down, this is not coming from my spin or muscles and will only ease if I get up servral times throughout the night to urinate. Worse if I lay on my right side. Had this going on for a few years but has gotten worse this past few months. Joints painful and feel gritty also have small solid lumps under the skin that when popped are hard gritty lumps of white calcium almost like a small stone . I also suffer from frequent sweating which I no longer beleive are menstrol related. I am a 53 years old female.
