I saw Dr Scott, not Dr Simmons. When I was originally referred to Hershey it was for a second opinion on Myasthenia Gravis, Dr Scott ruled auto-immune disease out and was leaning toward Mitochondrial Myopathy, but when the muscle biopsies were inconclusive, he said he couldn't do anything else for me. I never even thought ALS was on the radar until my GP mentioned it! Thank-you for your genuine concern!
