Gute Besserung!
Hope the doc prescribes you a massage by 2 fine, lightly clad redheads - though it's more likely the masseuse is a russian ex-weightlifter!
Probably you'll only get an injection to relax the muscles.
If you do a lot of heavy lifting you should also check for special back training, your intervertrebal disks will thank you.
Use the sick leave to regenerate, I'll do the same after my comparible hellish work week. I have some days off untill Monday - as soon as I am out of this madhouse today I will turn off the phone, submerge into my cave and do a video and game marathon.
