Rhett, I am bone-on-bone in my sacral and lower lumbar vertebrae. Only anti-inflammatories, opioids had worked in the past (this has been going on 20+ years, only recently did I graduate to the opioids). Well, I bought your 4"x4" patch and it has been nothing short of amazing! I lightly tack it over that area with medical adhesive (so it doesn't slip or "fall in" when I remove the clothes holding it) and now I am just taking a little anti-inflammatory in the morning, then I wear the patch until bedtime. No pain. I cannot wait to try this out at the gym next -- may graduate to the longer strip size! Thank you for creating this!
