You know, this is really commendable that you try to invent such devices as we live in a very developed world, but when you feel pain, there are no pills you can use for relieving the pain. I am talking from my experience. A few years ago, I had unbearable knee pain, and there were days I couldn't walk at all. That was chronic pain, and doctors couldn't help me. Thankfully I found the solution as one day I met a person who had the same problem, and he advised me to try kratom, and also he recommended me a site
where can i buy kratom. I was sceptical from the beginning, but I decided I have nothing to lose, and thankfully kratom helped me to relieve pain instantly.
