Question
I am experiencing pain every morning starting around 4:00AM in my middle back on the right side of my left shoulder blade.  I'm an active 40 year old female and have not changed my exercise routine or experienced any injuries or strains.  Within an hour of waking, the pain is gone.

Answer
Rose,

Sounds like a muscle spasm.

Rather than an injury or strain, it could have to do with a common working position or activity, such as use of a mouse.

For more information on mysterious ("idiopathic") pain, would you read my article on pains at somatics.com/page4b.htm and feel free to contact me, again.

with regard,
