You do have a lot going on!
I think the move sounds great! You can still go into Motor City when you want and have more quiet, safety, less to clean and no stairs. Sweet!
Reading your post I am struck by the history of trauma yet the lack of any major complaints about it, aside from grinding pain which had a cartilage explanation. Not much sounded like a chronic nerve pain issue.
the broken toe that discolored and felt like it had a tourniquet on sounds more CRPSy IMHO. In order to have CRPS you have to meet the Budapest criteria. If you didn't have discoloration or temp differences until 2011 I personally have a hard time biting that it was CRPS. You likely had some nerves compromised with all the earlier trauma that just finally said "enough already!"
I too have struggled with the question of when. I had obvious but not severe CRPS symptoms with my initial injury but they resolved, then came back after my nerve was injured. Then my nerve surgery made things much better but I went south after needing another procedure on the same foot later on. Seems like a theme here of our limbs have been messed with multiple times and CRPS finally showed up. I sort of feel like I was flirting with it a while but it didn't get going fully till 2014.
Unless your leg/foot/toe was purple or red like it is way, way back I say go with the later start date, earliest 2011. Personally, I would still go after treatments that fall in that window unless there is risk of spread with them.
I read an evidence based research article recently that showed better results with ketamine in chronic CRPs tha early CRPS, allaying much of my worry about having waited too long....
best to you with the move! be careful and take care of yourself!
