TGA medical?

Hello everyone! After years of time spent in many a closet, or wooded area i have decided to grow some emdical for my back spazm and nerve flares. I want to grow some TGA gear i heard some of their stuff is medical. If not i am still seeking relief. Anyone know of strains readily available from soem big named breeders that offer the narcotic relief im looking for? Any help would be much obliged!!

Thanks,
