"i suffer with fibromyalgia mostly in my upper back and both sides of my neck. flector patches are incredible! i had been receiving pain shots for years to relieve the muscle pain that in turn caused me to have migraine/tension headaches more than 15 days per month. the major problem is that insurance does not cover these patches and i have drained my dr. of all of their samples.  i highly recommend them if you can afford them!"
