I have a neighbor who two weeks ago I saw limping around. He said he has a lot of recurring pain with his ankle that also bothers him when trying to sleep. His doctorpreviously told him it was arthritis and prescribed pain bills which has not given him much relief. I told him about Actipatch and to look up on his computer about it and see if this would help him. I just saw him while walking my two dogs. He came out to tell me that he ordered the $10 test product to try. He said it took a day or so but it actually works and appreciates the recommendation I gave.him. He has received pain relief and stopped using pain pills since it actipatch works so well. I couldn't tell he had it on even though he was wearing shorts. He show me what foot it was on and it was not really noticeable. He plans to order the longer lasting battery one since the test product has a shorter battery life.
