Do you have symptoms that you don’t have a reason for?  Did you not feel satisfied that you had enough time to fully explain your symptoms or concerns? Did you feel rushed and fobbed off by your GP or physician? The advantage of a private appointment is that there is more time to explore your symptoms, do an unhurried comprehensive examination and then ensure that no diagnosis has  been overlooked. Hopefully this will lead to a diagnosis or peace of mind that there is nothing wrong.
