I have lower back pain, usually in the evening or when i have sat down or lay down for any amount of time. My legs (from my knees to the top of my thighs) are feeling like they are cramping up - or like I have really tight jeans on - but I don t have them on. I have got haemochromotosis - and have abnormal liver function.
Lower back pain has many causes, but I agree with your doubt
