Looking for back pain relief... Picked out some strains, feedback please

I broke my back five times in ten years and now have arthritis in my spine along with severe osteoporosis everywhere.
I use indica based hash with the plants taken at the extreme end of flower,works like a champ and I sleep like a baby.

Grand Daddy Purple was among the best indicas I tried in terms of high. No idea for pain.

I use tumeric, fish oil, resveratrol for inflammation in joints or in general. Product called Relief Factor has all those in it plus another substance. That works too. Use olive oil instead of the others, canola oil is supposed to be bad.

Bubble hash is great for pain. Just score some 5 gallon bags and use your trimmings and larf buds. Super easy and worth the minimal effort.
