I Think your pain comes in the nerve pain catagory same as me.......so I'd say Anything Afghan/Kush.
Afghan dominant is like a sledge hammer ain killer for me...with little finesse.......sometimes you Need the sledge hammer....
Going Afghan Kush just Adds Finesse...IMO......Best of Both Worlds.....
When you grow your OGK.....let one go Over if you can....Keep it for Night Meds.......
