“The Neuropathic Therapy Center at Loma Linda allows me to live my life.” For Mark Knowlton, age 61, those words are no exaggeration. Mark walks, drives, does yard work, and plays with his grandkids. In the past year, he has been downhill skiing on a top-tier slope, gone boating, off-roading and fishing, and visited the Grand Canyon. He has done all of this despite severe neuropathy (nerve pain), tingling, and numbness in his hands, feet, and lower leg. Four years ago, the former college football quarterback was diagnosed with metastatic pancreatic cancer.
