My elderly relative has recently started moaning and groaning all night although he says he is not in any pain. [Arthritis in his legs can hurt when he moves his legs but otherwise is manageable]. This isn't good for me or the neighbors. Does anyone know of any techniques that might help him relax and get some sleep, or at least stop the verbalization? I've considered over the counter sleeping pills but I'm afraid they might just make him more anxious. Any advice would be appreciated. Thank you.
