"Bad and dangerous advice"

I’ve had terrible back and hip pain and self referred . I was ask a few questions and I informed them that I’d had lumber surgery in the past. I was told I would be contacted regarding an appointment but got a email advising me to do some exercises for 2 weeks then if I still had a problem call for a in person appointment. I’ve been advised by my osteopath that the lumber extension exercise should never be performed by someone with my back history. My symptoms are now so bad I’ve been prescribed liquid morphine. I find it absolutely disgusting that these people and service is giving people medical advice on the strength of a phone call. Surely this has to stop.
