I am not a doctor but work in health care and see around 30 people each day.I have good days andbad days like everyone, most of my bad days are caused by patients with trivialities eg if I lean on my elbow for half an hour it gets sore, if I have a lie in my back starts to feel a bit stiff. I dish out advice on Home ex, posture, weight loss and nobody takes a blind bit of notice. people fail to attend because they have hair appointments, football matches the list is endless. So when real problems occur it is sometimes easy to miss them. howevever thats no excuse and I would advise people with seriuos concerns to make a list of questions to ask and not to leave untill they are all answered
