CBD oil for osteoarthritis pain

I have found rubbing in proper herbalists strong arnica helpful, a good deep massage. I also take high dose turmeric daily, that's been magic, but a few - not all - have on gransnet reported their taking turmeric reduces iron in the body

Sorry to hear this greenmossgiel. I'm assuming you've seen a consultant, had an X ray etc? Are you needing a knee replacement? Long wait of course but you could be expedited up the list if you're at the bone on bone stage.
Sorry I can't comment on CBD oil. All I took pre and post op was paracetamol which worked well for me. Have you tried icing to reduce inflammation?
