Good to hear from you Bro! Was yours lumbar? I know to be patient, but as you know its SO HARD! I've probably lost 25lbs. I feel like I could do some light stuff... I did some push-ups and sit-ups last night just to see how I felt. Other than being super weak, I felt OK.
something you might want to try is using hand squeezers like Captain of Krush
when I was hurt I used those to keep up my grip and maybe it was psychological but when I finally did get back in the gym it didn't take long to get my strength back
