I recently got thrown from a horse and sprained my back very badly and it twisted my spine up so now I wear a brace to help relieve some pain. And I was wondering, is there any kind of stretching or techniques I could practice in Taekwondo that I could do that wouldn't cause strain on my back from the injury? Because I feel like if I don't practice while I'm still healing I will lose some skill or technique in that time during the healing process. Or do you think I should just let it heal before I get back to it?
