Oh man, Bobert you done gone got your self in a mess now boy. Don't rightly know if I should put my opinion of most chiropractors in writing, but I do know the pukka Physio, trains a lot longer for the job, so knows their way around best.
Anyway, I hope you get some ease for that spasm, and try drinking from smaller glasses to reduce the strain on your back.
Hoping you get better quick.
