I have suffered from diagnosed migraines since I was about 6 yrs. old. I am 60 now. My neurologist says my migraines will only get worse. How effective are the Pain bands? I use the Sleep bands and find them to be extremely effective. Also, I’d like to know how long these bands last or how long they are effective? I’m also interested in the Weight Loss bands. I don’t have a great deal of weight to lose … about 30 lbs. Most importantly, I’m interested in the Pain bands, as I have severe head aches. I’d be most appreciative of a response at your earliest convenience. Thank you.
