I found this study to be worth sharing. I know many with Periodic Paralysis deal with pain 24/7. I can't help but wonder if those of us who have severe, chronic pain happen to be associated with SCN4A or other sodium channel mutation.
I feel it's relevant to note (not only to those with HKPP but also to the general public) that I have monitored my sodium intake over the past few years, and found that not only does increased sodium cause me to become weaker due to potassium shifting, but it also greatly increases my chronic pain level. I think it is also important to mention that sodium (as well as glucose) causes potassium to shift even in someone who does NOT have Periodic Paralysis. This process happens in "normal" people. For that reason, it has crossed my mind many times that chronic pain and chronic fatigue syndromes could be related to sodium.
I will share more at a later date, but wanted to go ahead and give you this article today.
I think I responded to everyone who emailed me over the past few weeks. If I didn't, please feel free to shoot me another email and fuss. I'll get right on a reply.
