So yeah, been doing Jujutsu for a little while now, and did Judo a couple years back. I really have enjoyed both alot, and feel they've added a tremendous amount to my Karate. Thing is, I have some major back issues, including but not limited to bulging a few discs over the years, and having to wait for them to heal. Plenty of other little injuries here and there too..but this is the one that makes me worry with throws. So, one of them has started acting up again, getting the ol' sciatica coming back and i'm kind of scared to continue training bigger throws due to this. The two things I've thought of are either stopping completely (don't want to if it's avoidable), or trying to find a crash mat. Before it gets brought up, my ukemi is good, it's those times where things don't work out 100% that I can feel it wearing on me, and the simple of falling (no matter how good you ukemi) seems to have a cumulative effect - especially at 210lbs or more. Any of you with experience taking bigger falls consistently as you get nearer to to 40 or so? I feel like i'm just starting to hit the age where I really need to be more careful, I would like to continue doing this, but i'm not willing to sacrifice health for it.
