Its possible to get treatment on the NHS, but many people prefer going private.
Im on the same position as you, i cant go private im still in school.
last week i went to see my GP. He told me to get the blood tests and come back (He said after the blood test we can look at options like surgery, When you go to your GP tell him how its killing you inside and you just cant live with it anymore.
Btw this is my first post so ill just like to say Hi to everyone.
