Et tu, back?

Och, my lower back has gone from zero to super jacked over night — came home early from work today as I was having difficulty concentrating.  Stretch, stretch, nap, hydrate, stretch, heat, stretch and more stretch is the order of the evening.  Plus a good set of tennis ball grinds into the back against the wall.  Very odd… I’m hopin it rides away tonight as quickly as it rode in.   Massages, tweaks, medicinal kicks and presses welcome!
