yes, stick with the indica's for that deep joint and muscle pain. any afghani cross (bb and all the others) should help. i'd also recommend a pain management doc if mj isn't always handy or can't keep you comfortable. i too am afflicted but mj isn't enough. it has cut my pain pill intake in half tho...
get in touch with dr greenthumb and i'm sure he can match up the strain to your needs...

nevada isn't a bad place to move to either. we legalized med use in 2000 and decrimmed an oz possession down to a ticket.
