I have CRPS/RSD. My neurologist recently said he thinks I have some type of myotonia. I was wondering if symptoms of myotonia are also symptoms of RSD. I get severe muscles contractions and muscle weakness. When I get cold my muscles freeze up and make it impossible to function. I am unable to function until my muscles are warmed up by heat of some kind. When the muscles freeze up it's like being paralized. The colder I get the more muscles in my body freeze up or contract and the harder they contract. It is also very painful. I have intense sweating and muscle contractions when I am asleep at night. The contractions are painful and wake me up. Due to the strong muscle contrations, I am struggling to keep my range of motion in my joints. Is this typical for rsd patients? Thanks!
