Hello, this is my first post even though I've been reading the boards for a while. I'll introduce myself first.
I've been practicing Pekiti-tirsia Kali out of Salt Lake City under Guru Wihongi for a few years now. We're one of Tuhon Gaje's pit bull schools. We're a pretty informal tight knit bunch.
I damaged my rotator cuff my senior year of wrestling. Honestly, I only half heartedly did the excercises my physical therapist showed me and it didn't get better. When I started training with the stick I did alright, but when I started going full power it hurt bad. So I started doing the physical therapy excercises and I found that the stickfighting motions complemented it very well. It definately sped up my recovery. As I moved on to hand to hand I realized full power hooks absolutely killed, but I took it slow and worked my way up to it and they don't bug me. Now every once in a while I'll feel a little weird when I throw elbows, especially on an upward angle, but it doesn't hurt anymore, and I still do the excercises.
Sorry I'm so long winded, I guess my point is that I know your pain, but recovery isn't as hard and long of a road as many people (my physical therapist) make it seem.
So start training, you'll love it, and good luck.
