My back feel pain, is it any problem with my kidney?

POSSIBLY Kidney. The location of back pain is important. 'kidney pain' is usually in the mid-back not low back--generally. A kidney infection is usually 1-sided with fever and usually preceded by a bladder infection. A kidney stone also is usually 1 sided with pain radiating to groin with blood in urine (or dark urine). Back pain is a very common problem usually due to muscle-skeletal problems. Hope this helps.
Probably not. Back pain is very common and kidneys usually only cause this if infection or kidney stone is present; otherwise, another cause is usually present, such as musculoskeletal, pelvic disease, urinary tract, or female organ disease. Rarely prostate problems may cause this, but usually other symptoms are present as well.
