I'm new, duh, and I'm sure this has been asked before: I am on a hunt for the best strain to use for upper back/muscle pain. I have an upper back injury and have had it for 10+ years. I stretch, take care of myself, etc... but still, sometimes it gets mad and at these times it is VERY painful. I can't turn my head, sometimes my arm/hands get numb. Ouch. On top of these flareups, I have chronic pain (2-4 out of 10) every night after work. Some strains make me hurt worse; i.e. I am more hyper aware of all the pain in my body. No fun. Some strains seem to relax me and I care less about the pain. Trouble is, I don't know what strains I'm getting because I get whatever comes in the little baggy. Any advice? I'm pretty sure Indica is the way to go, but what are the best for this within the Indica family? Some mentioned Chronic, Medicine Man, and Devil, but I can't find these seeds locally and dude, they are super pricey. Any help is appreciated.
