We don't have any Nurse Practioners in our practice which is a shame. There is a lot of confusion between the term Practice Nurse and Nurse Practioner I think. This is the definition
"A nurse practitioner is very different from a practice nurse. The practice nurse is the person who provides nursing care such as dressings, immunisations, travel advice and cervical smears. In contrast, a nurse practitioner's daily clinical work comprises the examination, diagnosis and prescription treatment of common medical problems such as chest pain, breathing problems, high blood pressure, coughs, feverish illnesses, ear, nose and throat conditions, abdominal problems, joint and bone problems, infections, tiredness, breast lumps, gynaecological problems, and skin problem"
I'd make the appointment with your GP, as others have said, Cyclinggeek and you can then cancel it if the nurse can't prescribe.
