Having Severe Back Pain While Sleeping. History Of Bladder And Kidney Infections. How To Get Relief?

Question: Okay so this has been going on for a while. I thought maybe because of my mattress but Ichanged that over two years ago. I always thought that i couldn't sleep in because of having poor sleeping habits. But now I am realizing that I am waking up more and more during the night sometimes three four times because of a pain on my left side towards the back, I thought maybe because i had to go to the bathroom, perhaps gas, perhaps poor posture, I have no idea, But the last year I even went to the hospital in the missle of the night because I was litterally crying from the pain. I have had bladder and kidney infections but more when I was younger. I might have an infection once every two years now, but that pain is usually in my shoulder blades. I am noticing that when I wake up and go sit down there is a burning sensation (like creeping) towards the lower left of my side and down my leg.. I joined 3 months ago a gym thinking I was out of shape, I should loose another 20lbs but I am doing 5 hours aa week at the gym, running, bike and weights. It has not changed my pain in the middle of the night. I am female 47 years old. I was in Jamaica in March and had a real bad time with this. It spoiled my entire time, since I could not relax or sleep well. So I thought i woild look for some answers.Oh yes one more thing. I had my right ovary removed 16 years ago. I went int o tie my tubes ( i already had three children) and the docotr found a mass on the ovary and removed it. I had a gyno appointment two moths ago and besides fibroids everything seemed normal. Thank you

I just did blood test about two months ago and I do them yearly. Everything comes back normal. I just called my doctor and I have an appointment on thursday. I will keep you posted if know anything else.
