Any info on stretches or exercises you can share?
Boy, they would be pretty hard to describe with words.
"WonderWoman" for upper back.
Hold arms straight out front parallel with ground.
Move them forward stretching upper back.
Then bending at elbow pull them back, stretching chest muscles.
PT had me visualize all the muscles, large and small.
Refer to a muscle anatomy illustration.
Lower back.
Sit in a hard chair, ankle on knee and lean forward at waist,
stretching lower back, glute, and hammie muscles.
Do both sides.
Repeat thru the day, a few reps each time, gently it doesn't 'cure' fast or all at once.
Too much can cause more pain.
