I am sorry to hear about the pain you suffer, I can atleast function on a semi normal level, I just cant work at a physicaly exerting job for long durations of time.

I feel like a truck hit me in the morning, but this usually subsides with light motivation after a few hours, nothing extremly phsyical atleast for long durations, I was always the type that worked from dark to dark, in the past.....this was taxing on my body, but I felt it made me strong, at the time I looked it atleast, and may still do.....but the irony is real, I dont feel half as fit as I may look and have damaged joints that cause arthridic conditions that seem worse in the winter...but atleast managable for a good part

again, sorry about the struggles you are enduring

kind regards
Eddie
