I have been suffering from back pain, pain in buttocks, leg cramps, leg pain going down one or the other leg, sometimes both, painful thighs, knees and calves. I am currently care giving for my wife who is awaiting hip surgery (in New Zealand where waiting lists are as long as five months). I get very tired but cannot always sleep because of the leg pain and cramps. I am not on any medication except Ibuprofen and paracetamol which I take regularly day after day.
