Dude, been there. I can not only sympathize, I can empathize. Only toothaches and migraine headaches compare to a thrown back for a guy. Got mine dinged up when I was in a chopper crash. As I age, it goes out easier and takes longer to get better.
Heat and rest (and the odd whiskey) seem to help the most. Pain meds only hide the pain and you can re-injure yourself when you feel too good too soon.
Black holes are where God divided by zero.
