Lots of good info given already...
I was "middle aged" when I started to have multiple work related /repetitive motion injuries. (neck, shoulder, arms, hands, elbows..)
I had to navigate through the work comp system & delays... and stop working to see any real healing . It took about 2.5 yrs for me to get back to 85% of normal.
I figure 1 yr of that was wasted due to the wc & delays and PT early on while I was still working..that just did not work..

So usually a younger person with really good care team and focus on a ton of self care - this isn't something only a PT or CD or MD can do for you , you have to do a lot of the work on your own.. *As long as there isn't something surgical that need attention..*

As mentioned earlier explore all the sticky threads. Great info there.

Passive posture work & awareness & easy stretches, just to the point of resistance not beyond it.
