I have knee issues and I had tried everything, therapy, aqua aerobics, NSAIDS, and nothing was helping until I saw a commercial for Fire & Ice. I figured, why not? I can return it if it doesn't work, right? So I purchased it along with some gummies for energy. The Fire and Ice worked immediately. I was able to get up and walk away from my computer, or couch, without having excruciating pain for the first minute or so. My husband saw what it was doing for me so he decided to try it on is spine that is developing arthristis and he said it made a big difference. We put it on morning, noon, and night and are able to have a pretty pain free day. Thank God and thank you BATCH for helping people like us feel somewhat normal again.
