I rotate so many topicals and like Ultra Tiger Balm too. I use Vicks and Menthlatim and a chinese oil and I use DMSO as I belong to a DMSO group. Topricin worked so well for me early on and whether knee is just getting worse, OA doesn't reverse, it's not as effective, but I still buy and use it. These keep me going as I don't want knee surgery....

I even mix a concoction of my own with a Vit E base or Aloe Vera base, chop up aspirin, add drops of DMSO, mix it up and brush it on my shoulders and lower back.
