The back pain story line is bloody ridiculous.
a) if you have back pain that bad after a serious injury, over the counter ibuprofen and codeine would be doing fuck all especially after a few years of taking it regularly. Might as well be eating smarties. And likely he’d still be on prescription opiates given that he does seem to still be in a lot of pain.
B) if he’s having terrible back spasms, he’d need to be on muscle relaxants, codeine wouldn’t do shit and he definitely wouldn’t be able to drive.
