The Back injury and nerve damage can be slow to heal, I had to clump along for a few months, not able to control my foot for a while. I still remember the sci-fi dreams from pain, meds, and lack of sleep.
The good news, I don't even give it much thought these days. It will get better Sounds like you are keeping your spirits high, hang tough.
