I have a metatarsal stress fracture that hasn't healed months after the injury. I've been wearing a walking boot for the last three weeks without much success. After three weeks i tried not wearing the boot, but the swelling came back. Sadly, this affects my back swing so no golf so far this season! Is this possibly related to CLL or just the fact that at my age (70) bones heal slowly? Other than CLL I'm active, not overweight, and pretty healthy. According to a recent lab report my calcium levels are fine.
