Nasal Polyp

Several months ago I began having episodes of dizziness (the best way to describe it, though it really felt as if I had something sitting on one side of my head) and was sent to a neurologist to rule out anything serious. The neurologist informed me that he believed I was having migraines, but wished to perform an MRI just to be safe. I recieved a letter from him a few weeks ago in which he stated that there were no sinister findings, though there was an "incidental finding", a polyp in my right nasal cavity. He stated in the letter that this was probably nothing to worry about and that he did not believe that it had anything to do with the dizziness.

I have had no symptoms of a polyp...no nosebleeds, sneezing, or blockages. I had never even heard of nasal polyps until this happened. After recieving the letter I looked the subject online and read that they were benign and nothing to worry about unless they started to cause problems. I only read one article and chose not to delve much deeper into the subject. Well, I spoke to a good friend of mine today who told me that she had the same thing happen to her a while back, and though I should not worry too much, that I should go to see an ENT to have it biopsied due to the fact that I only have it on one side. I have a tendency to worry about my health (since I quit smoking...ha) and so I decided to go searching online for info about one-sided polyps...seems I really may have reason to worry according to a few ENT websites. I should mention that I was diagnosed with HPV several years back, which seems to put me at risk of Inverted Papilloma.

I suppose I am just wondering, should I trust the neurologist on this, or should I see an ENT right away? I am also in the process of moving back to the US from the UK, and I really do not have time for hospitals and biopsies and such. I do not want to worry myself to death over this. After I quit smoking a few months ago I started developing health anxiety, and have only recently began to feel more like my old self. Part of me wishes I would have never said a word or looked online further, because I can already feel myself getting the anxiety back. Any help or info would be greatly appreciated!
