Having a label for your condition is a gratifying and important step, congratulations on finally figuring that out. Once I had a label for the source of my pain and problems, I felt I crossed a mental threshold where I could put it in a box and contain it. It was no longer an overwhelming question mark floating around. I hope this is a first step in many more improvements for you!

I don't know what to say really. I've been hesitant to engage with this place, but didn't want to leave you hanging without a reply.

I spend most of my day stuck laying in a bed or on a couch after lots of broken stuff in 2014. No one has been able to say exactly what is wrong with me as far as what didn't heal. I just can't hold posture sitting or standing for more than around one hour. I've slept doing a bad impression of a rotisserie chicken for nearly 10 years. Tired would be an understatement. I also only really go out normally for medical appointments. I can do a daily physical exercise routine. That is what has held me together so far.

There are physical therapists who specialize in CRPS/RSD. It might be worth finding one to work with your knee.
