Welcome to our forum! We have information on this page on how to go about getting a second opinion which I hope will be helpful to you. You might also be interested in finding out more about how to go about getting private treatment - whether you need to be referred by a GP - on this link from the NHS website. You can also find out more on the question of whether your NHS treatment would be affected on this page again from the NHS website.
I hope this helps a little and that you will also hear from some of our members who have gone down this route before.
