I have issues with chronic pain mainly in my back due to old sports injuries. Luckily a few years ago I found Kratom which has completely saved me from being in pain all the time. Personally for me Greens work best. I found Green Maeng Da and Green Bali work the best for my pain. Whites are a bit too energetic for me. But green is a long lasting clean energy which also helps me focus at work during the day. The best quality kratom I have had success with has been from MitraSpec.com they ship really fast and takes credit cards which is the only way I can pay and makes buying on their website super easy.
