I know questions about the Osmo patch are dated, but thought I would tell you I ordered and used the Osmo patch during 2012 with pretty good results (for a baker's cyst). It is drug-free and works while you sleep. There were 10 patches and adhesives in the box. I wore the patch for 10 consecutive nights. I noticed about half way thru that there was a good difference. When I straighten my legs out in a recliner chair it usually hurts. Now I wasn't feeling any pain. It got better, and then about a week after they ran out, my leg started hurting again. So the problem is, you have to keep ordering, it is not a cure. I noticed when I removed the patch each day there was a light stain on it, like a light bloodstain altho no spot on my leg. To order I went to Osmopatch.com and paid w PayPal to Merchant MediWise Pty Ltd. With shipping and handling the cost came to $49.90. There was no problem with the shipping. The only problem I had was their adhesive did not stick good to the leg, I had to use additional adhesive.
