question: chronic aching in left hip, progressed to middle-left back and left side of rib cage, now neck and left shoulder are stiff and aching. Still able to move, but in pain. Right armpit recently started to smell sulphurous, whilst left armpit smelt of onion (not unusual for me). Then more recently in last few weeks, urine had sulphurous smell. Have had subtle ammonia smelling sweat around groin for many years. Kidney failure? I thought I was relatively healthy!
