i go to sleep and wake up with really tight pec muscles

does this happen to anyone??

i actually feel better after i get up and move around. it's not like im exercising in my sleep

I'm that way in the mornings across my shoulders & upperback, sometimes my arms too , depends on how I was sleeping.

is it bad circulation? do you think the muscles actually GET TIGHT or is it in my head

i guess i need to go back to sleeping on my back

For me I'm pretty sure it is chronic myofascial pain/syndrome.
CMP?

I had been feeling the same way (a hot morning shower would loosen me up). I have returned to wearing my Intelliskin Tank to bed the last few nights and I am waking up feeling much looser.

I'm a side sleeper BTW. I'm told sleeping on your back is healthier but I have never been able to get a proper night's sleep on my back.

I might do that tonight! Never occurred to me

Yes, for me, this happens from lying on my back at night. My body weight causes compression - from back to front. Everything in there is so close together!

When the back things (shoulder blades, muscles, ribs) press or 'pinch' the middle things (thoracic outlet areas - nerves, arteries, veins, scar tissues, etc.) up against the front things (collar bone, ribs, muscles, etc.) I get pain and swelling in my arms and hands and tight muscles (pecs too). It wakes me up many times per night.

Can't lie on my stomach, can't lie on my sides, now lying on my back has limits. Glad I have an awesome recliner!

Another reason why weight control is pain control!

Hang in there girl!

Same here, a hot shower and moving around really helps. Moving around after waking up really helps loosen up those tight muscles.
