I've been driven hard and put up wet. If I were a gun I'd consider myself a project gun. Played college football two years too long. Both shoulders need rebuilding, back is my most limiting problem but my knees are still serviceable. Don't take any pain meds and have chosen to just keep going as long as I can. Weight control has helped a lot. If my father can walk a mile and a half at 95 I can do a miles as is.
No Rx will fix nerve pain and having my own DEA number is too great a chance for self medication problems. I've seen dozen of other doctors fall into that trap. Pain, you just have to get live with and get on doing what you want to do. I was 28' up a ladder, cleaning out gutters Saturday, just in time for 3" rain Sunday. Heading back east in a few weeks to thin out the duck population. Just keep grinding.
