I wish there were an option to rate a post with a great big hug. So sorry you're having a rough time right now. The next 36 hours after my first physical therapy appointment were very difficult for me, increased pain -> 1000 mg uncoated Tylenol --> tummy turbulence --> friends needing to run out to drug and grocery store for OTC meds, saltines, bananas.
Have you seen the gentle stretching exercises
@Roy Gardiner has posted? He was kind enough to put a link on my thread Sarah Jane's Summer Journey. They might help. There's something in the library, too, about the timing of returning to work. I seem to remember it advocating 12 weeks of rest and recouperation if possible, and a gentle staggering of hours from partial days to full days. I know not all employers and job situations permit that, but IMHO they should. It's hard to imagine being productive when you're still dealing with physical pain and discomfort. These words are coming from someone who pushed and pushed and pushed herself through all sorts of fertilizer for several decades and now sincerely regrets forcing her body and psyche through that much stress, pressure and discomfort. But, as they say, your mileage (and work situation) may vary.
I hope that the Tenth Doctor isn't dismantling a Cyberman to obtain parts for your joint replacements! Or is this how the Eleventh Doctor ended up with his companion, Handles? (Forgive some Dr. Who references based on Christine's current avatar, but I couldn't resist. Resistance, after all, is futile. ---- Wait! Different British actor as lead in difference famous cult sci fi series.)
