Worried about Recurring Throat Cancer: Oct. 23, 2011

Hello,
Last May, I had my five year check up with my throat doctor. Everything looked great and he told me that since everything has looked good, that he didn't need to see me for 2 years unless I had problems. (Five years ago I had squamous cell c. on the vocal chords. I had surgery and that was it. No chemo or radiation. They got it early and I was lucky.)
In August I broke out in a rash under both arms, on the sides of my breast and on my chest. It was very itchy and after many cremes, shots, a biopsy and dermo visits, they decided to refer me to a allergist. (The biopsy showed sensitive dermatitis.) This allergist appointment is in November.
Since August, I have changed all of my lotions and detergents to hypo-allergenic. Today, the rash flares up and down.
In September, I started to get a sore throat. I didn't think anything of it. I thought maybe a cold was coming on, but it didn't. I have lived on cough drops to soothe the pain. Three weeks ago I decided to go back to my family doctor and fill him in on what was happening with the rash, since I had started with him. I also wanted him to take a look at my throat and see if it was red. Well, it wasn't. He decided to put me on a reflux medicine for a month.
Last week, the rash flared up again and I called the dermo to see if they could speed up the appointment for the allergist. After talking to the dermo nurse on the phone and telling her about the sore throats and my history, we both decided that it might be best to give my throat doctor a call. I was really hesitant because I didn't want to waste anyone's time. My throat doctor had told me that horseness and a sore throat was a red flag. I don't have horseness but that sore throat has been around since September and they are consistent.
Anyway, I emailed my throat doctor's nurse and told her what was happening with my body. I now have a cough that comes and goes. She asked me if I felt like it was in my throat or chest. I told her my throat. Today, my neck feels sore off and one, almost like having the mumps feeling.
I have an appointment with my throat doctor this Thursday. It is a 2 hour drive to his office. My husband says that it is better to be safe than sorry. I have done some research on the internet and alot of what I have read says that if the cancer does not return within 5 years, things should be good.
Has anyone had any experience with recurring throat cancer? I am interested in knowing if the rash has anything to do with it also. A friend of mine said that her sister was diagnosed with stomach cancer this summer and she started out with a itchy rash. I asked my dermo about this and she said that she had read about how patients with cancer have been developing rashes early on.
I am a teacher and it is very hard to teach when your throat feels thick and sore everyday.
I am anxious to hear from anyone with any of these symptoms. Thanks!
