I just started P90X last week and on Wednesday pulled a muscle in my neck/shoulder/upper back doing KenpoX. This has been a trouble spot for me in the past, lots of knots in my upper back, but nothing like this. I get pain whenever I move my head in some directions. Thankfully Thursday was my rest day, but I still didn't feel like it was ok to work out yesterday, and I'm sitting on the couch wondering about working out today. I'm feeling really motivated but I don't want to aggravate this injury.
Advice? Today, ideally I'd be able to do the back and chest workout and plyometrics. But I'm wary, and of course it's a Saturday so I can't get in to see my sports medicine doc.
