Hi I was wondering if anyone could tell me if there are any known side effects of using the nikken biaxial powermag?  I started using it about 10 days ago.  I use it at night while I sleep.  For my Peripheral Neuropothy pain.  I dont know if it helped with the pain or not but 2 days afterwords I started feeling severy cold.  Now it's been 6 days, and no matter how many sweatshirts I wear or how many blankets I put on, I'm still cold, but I am also sweating tremendously.   Who can I contact to find out if this is a side effect?I have never felt so cold and so drained of energy in my life
