Do you have any specific areas that are causing you the most grief or issues? You can search the Virtual Mobility coach tab (https://thereadystate.com/virtual-mobility-coach/) to search by area where you are experiencing the most pain. I would try and prioritize what issues are limiting you the most first before trying to attack everything at once.
You have always be an active individual so with these windows of relief you are finding with these routines trying incorporating any activity you can, even if it’s just walking. Trying building up your base of tolerable activity gradually. Its important to take a whack at these issues yourself but if you are still not finding success on your own its going to be worth taking the time to find a practitioner that can partner with you to address your issues.
