Holy shoulder pain!!

Felt great last night, but woke up this morning with intense left shoulder pain. Woke up on my left side with my left arm folded under my body. As I tried to role over to get up...the shoulder pain was sharp and painful. Self-evaluated and I believe it's my supraspinatus and the long head of the biceps. Prognosis: a few nights of sleeping on my back should return it 100%..hopefully. I've had issues with my right shoulder in the past but the left one has held up to this point. It's amazing how the wrong static positioning of a joint for a length of time can actually cause injury. This is the case for probably the majority of low back pain diagnoses out there. My body hasn't felt this good in a very long time...except for this shoulder "injury". Will keep you posted on the progress. I'll make a last minute decision whether to train today or not. Even if I didn't train today, I'd still be on track for 5 days this week. We'll see.
