Upcoming ENT Apt for right side neck and ear pain. Support Please

Hello, 

I'm fresh here. Hope you're all doing well x

I have Silent Reflux and Post Nasal Drip. Since treatment for these, my symptoms are improving and in better control. 

8 Weeks ago I started having right side neck pain (not a sore throat, but a structural neck pain) which causes daily right side ear pain. 

I was referred to ENT last October for constant throat hoarseness. This still continues to affect me daily, even if not as obvious to others. but I know there's a raspiness and weakness. 

I was on a routine waiting list, but was able to expiate my appointment and now have one offered later next week. 

Despite these symptoms, I feel generally well, no weight loss and full blood count normal. But I'm starting to mentally prepare that I may have a head or neck cancer. 

Please can anyone either give me advise on what to expect/ask during this appointment, what to ask/check for, or anyone can share their experience with similar experience (either diagnosed with a cancer or not). 

I'm particularly anxious as I have a 5 year old son who is my whole world, and it's frightening thinking I may be fighting for my life right now 

Hope you all are doing well x
