For pain I would grow a high CBD and a high THC cultivar then you can mix match and combine the two for a custom blend of THC/CBD.
Maybe something like Candidia for CBD and Blue Gelato #41 for THC.
61 yo here I am basically pain free because of cannabis and it keeps my blood pressure low.
you would enjoy compassion lime then only thing is its smells so strong lol , its a 10/10 thc/cbd strain easy to grow and can buy in auto form
