I think I’d be speaking to the practice manager. Your husband has been prescribed heavy duty painkillers and a muscle relaxant by the pharmacist that are ineffective, the physio hasn’t helped. Therefore you’ve followed surgery protocol which has failed and need the next step. I’m horrified the physio hasn’t referred on. He needs a GP assessment urgently, if you still can’t make one via a receptionist be firm and speak with the practice manager. This is not ‘normal’ back pain, their processes have failed, a different assessment is needed urgently, no one should be left in that level of pain. Good luck.
