Pulled muscles in sleep

[pancakes222]

Whenever I wake up I always feel like I have pulled my chest muscles. I always thought it used to be from sleeping with the kids but even now when I have slept alone and regardless of how I have slept I wake up with pain across my chest/into armpit. It lasts for a couple of hours in the morning and then eases off. Any ideas?

Torn rotator cuff? Have you injured your shoulder at all?

Could it be indigestion ?
My friend once broke her big toe in bed !
