I have been suffering from lower back pain for several months now which mostly occurs when laying down in bed at night or sitting. I went to the GP and the doctor ordered a routine blood test to look for inflammation and it showed I have an iron deficiency but the pain in the back has obviously not been resolved. Taking painkillers is doing nothing and the pain has been getting worse and I can barely move on the bed to get comfy and am waking up due to it. Is there anything I can do?
