End stage arthritis...

alright, I need both knees and one hip replaces...I wonder what relative I can blame for passing down this pain. So...can someone give me some ideas on what strains I should probably be looking for....I just ordered some NYC Diesel from Ontario Seed Bank last week, hopefully I'll get those beans shortly. I've got some no name growing right now, something that came with the bag of weed I got from my dealer, so I'm calling it Jane Doe. My Doctor said I need a strong indica with a high CBN count...or was that a CBD count...well, I would love a couch lock, the stongest they make, I would also like a good 50/50, but looking for the strongest Medical Indica anyone can think of...any suggestions please.
