After 2nd TKR, I had gastric bleeding from NSAID.

It is 8 months later and I still have pain. Physical Therapy was more difficult, painful and not as effective. Tylenol has not helped. Recently I asked my physician for pain relief; she prescribed Tramadol for 5 days. It helps so much. As it is an opioid, it is not good for longer time. My question is: can CBD help?
