My partner ,for the last year, has experienced a severe ache in her right leg? The condition only affects her right leg when lying down which of course means her sleep is interrupted. She is 65 and teaches 3 days a week. She teaches 5 to 10 year olds and rarely sits down!
Her doctor organised an xray on her hip but the results were negative - no problems were observed
Although she is against drugs two paracetamol seems to treat the symptoms and after a while she resumes her sleep
My question is "what can the cause be"
