Initially, I posted my situation in early October at which time I stated that I have Malignant Hyperthermia (diag. via biopsy, 1999) and that I was scheduled to see a neuromuscular doc for severe/pervasive muscle cramping/stiffness throughout my body (but primarily in upper back and lower legs)...at that time you replied w/ the following thoughts:
central core disease, myotonic dystrophy, and proximal myotonic myopathy. Since my initial posting I've had an EMG w/ results that stated "EMG showed SASD's in all muscles tested." WHAT IS/ARE SASD's? Note: I've since learned (over past several weeks) that my mother, 2 sisters, 1 brother, and a cousin have some similar symptoms.
My primary question is this: It seems as though many of the myopathies w/ symptoms similar to mine (e.g., Muscle stiffness, Muscle twitching, Muscle cramping, Increased Sweating, Delayed muscle relaxation, Pharyngeal Dysphagia, Poor/fitful sleep, Migraines, and Fatigue) are diagnosed earlier in life, whereas I'm 38 and have only started having problems in the past 3-5 years. More specifically, I've only started to develop these symptoms since my 1999 surgery, during which I had an MH reaction during a surgical procedure. I'd sure appreciate any additional thoughts. P.s., I have a follow up appointment for a muscle biopsy in 6 months. Sincerely, Steve
