the problem is my doc says come back if i am still worried but i don't know whether i should be worried. Some days during rushing about shopping centres my legs ache, my feet ache and my hip makes me limp. Some nights I wake with cramps from my hip to my toes (one leg). Some restful days I need to keep moving or my one hip, both sides of lower back , both kness, both ankles, get stiff and a bit sore and i battle to stand up straight initially. None of these are constant or totally predictable.
