I should have also mentioned I did CBD oil (Drops, roll on, balm that you rub on the knee) with THC, high grade, for three months with no change thus did not continue. This was most disappointing as a few of my coworkers got good results with CBD. But there is no clear evidence to support it despite the current market and popularity. Prior to this, I did turmeric supplement, both pill and liquid forms, with no change in pain after 2-3 months (but not at the same time as CBD). Like CBD, others got great results. So for some reason my body doesn’t even respond. And for me to keep taking all these products without any results, is too costly and wasteful.
