I kept thinking about a recent discussion of frequent heart rhythm problems on these pages among PMR patients. I have had plenty of heart rhythm problems myself- too slow (35bpm) for a long time, cured by a cardiac ablation, and then too fast (250bpm), cured by a big electric shock. I kept wondering if these electrical heart problems were related to my muscle cramping. The common factor is electricity, or to put it more precisely, faltering electrical systems.
So I looked up "inflammation and electronics", and was I surprised. I read an article in the NY Times "can the nervous system be hacked?" written only last year. So read the article, it is really exciting stuff. Just google "hacking the nervous system" and you will find it. They have put Rheumatoid Arthritis into remission with a nerve stimulator on the vagus nerve in the neck, no drugs at all.
