About three years ago, Kim Frasch of Tellico, now 65, had pain in both of his calves. Over time, it moved upward and became more intense.“As it got worse, it went into my thighs and glutes. And finally I began to lean to the left as an involuntary effort to gain some relief,” Frasch said. “My wife was worried I couldn’t stand up straight. I had sharp, stabbing pains in my legs, and standing was intolerable. I could only walk for a short period of time.”
