Hello and welcome to the A/P!
I am sorry to hear of your health challenges...and now this tension issue. It is very common with anxiety and chronic pain as well...so you may have a couple of contributing factors going on here!
Definitely follow up with the PT exercises that were given to you... (do you practice a piriformis stretch?)
...and check our the link below. It has directions for Progressive Muscle Relaxation, which should be beneficial to you.
www.stress-relief-exercises.com/Also check out our Resources at the top of the main forum page here for more great material to work with for anxiety management.
This should help you to feel your best...body and mind.
Post anytime!
