My partner was treated for osteomylitis when he was 13. He had surgery and bone removed and has some nice big scars. He is athletic and plays tennis and golf three times a week and is in good shape. Every so often--sometimes it is a number of months between episodes--he had a "bad" time with his leg. He experiences a lot of pain--enough to keep him up all night that is slow to respond to ibuprophin. This can last for a couple of days or on and off for a week. He hates to take pain medication and tends to put it off as long as possible. It has been decades since his surgery and there is not external evidence of infection on the leg when he has these bouts of pain. Can you tell me what is causing this? Is there treatment? What is the best advice on how to manage the pain?
