Residuals after 4 years…

Hello all,
4 years ago, I was on a vent for approx. 1 month, spent another month in rehab. and released with a walker.
I did become able to walk again unaided, but tired easily.
Today I walk with a cane, have some tingling in my feet still. Fatigue is a problem, also “numb skin” on my thighs there is sensation, but kind of muted…
Otherwise, I’m doing ok, but my neuro thinks this is as good as it will get.
