What Are Your Symptoms of Pmc?
I also have PMC. It is from my mothers side of the family. I live in Canada and because there was a lot of people in my family (or so I have been told) who had it in a close area some doctors got excited and we have been subjected to a lot of studies and test.
Apparently my family has a very unique strain which after reading some posts I'm not the only one so I question really what that means. We have been told that we have a potassium problem in our Nerves channels where (as doctors have explained it) our nerves are like gates that open and close to allow different ions to pass through them (sodium, potassium, calcium and chloride ions). And in my family's case the "gates" for the potassium channels either get stuck open or closed that will either stop all potassium ions or there is no stop to them which then cause the different PMC symptoms.
I have found there seem to be some differences in the symptoms among diagnosed people and I'm curious to know other peoples symptoms. For me smaller muscles are really only effected such as my facial muscles, neck, hands, fingers, toes and so on. When I get into cold conditions these muscles will "cramp" up like if I smile I might not be able to release that smile or shut my eyes tight or make a fist. In normal conditions I can reproduce the symptoms to a much lesser degree and it really only affects me if I close my eyes really tight or close my fist really tight for longer period of time. If I am exposed to prolonged cold conditions I will loose my fine motor skills in my fingers to the point that its difficult to pick up a pencil or zip up my coat. With even longer exposure to the cold larger muscle are weaken like my arms and legs but I am still able to appear normal and for the most part function normal. Those case are also rare since I don’t subject to myself to that length of exposure. With any of the symptoms I am able to "mask" them enough that at least people don't seem to notice. For me it’s just learning to use different muscles to zip up a zipper or pick up a pencil.
My uncle has experienced complete paralyses on more than one occasion after surgery. The first time lasted for about 3 days and it was determined the anesthesia they gave him for the surgery combined with PMC caused the paralyses. Doctors seem to be really confused on what to do with surgery and with my experiences they have always made sure the O.R. is really warm and put freshly warmed blankets over me as they wheel me into the O.R. I find it kind of funny like they don't really know what to do. I am told we can’t have non-depolarizing muscle relaxants.
