Physical therapy can help, but

ask the therapist if there are some things you can do at home to keep building.
This is useful for two reasons: 1- you can do stretches and resistance exercises with a theraband to great results and at your own pace..instead of doing 20 reps of one thing at a time, you can do 5×5 over several times during the day and still benefit without the soreness; and 2- these exercises are ones you can continue at home once your therapy sessions are done.
Key to this is YOUR motivations tho. It is really easy to put off doing them at home for any and all reasons. BUT, if you keep at them they help you keep whatever strength you have recovered.
In the future tho, should you get any new doctor orders for PT, be sure to ask that a ‘home plan’ be included on the orders. That way you will get the tools and guidance you need to [B]do it right.[/B]

Good luck and don’t despair.
