Hi Beccah,
Sorry to hear about hubby's sympathy running out.
I can relate as my wife losses it at times. She tells me that misses the old me and is tired of looking down at me in a wheelchair. I can see her point. This monster makes me a lot less of a man than I once was. But it is what it is.
My CRPS has gone full body and combined with a shrinking cerebellum it messes me up big time.
I too get blurred vision that comes and goes. If the metal in my body gets cold or hot the bone pain starts and triggers all kinds of stuff.
I can go on and on but I don't want to bore you.
Be well and take care...
