Stage 1 larynx cancer on right vocal cord progress. Not Happy

Hello All: Just joined this board tonight because I liked what I was reading about the same problems that I am experiencing after 42 radiation treatments for cancer on right vocal cord. I was diagnosed with cancer on Dec.6 2016, and two biopsys were performed via laryngoscopy. 1st one was inconclusive, second one was conclusive. My ENT at Cooper suggested I get radiation to remove the tumor from my vocal cord. During my radiation treatments, I didn't feel the effects right away until my second to last week of going to treatment. Bad sunburn on my neck, difficulty swallowing, mouth sores, and started magic mouthwash which still works to this day. My last treatment was on march 31st of this year, and still have pain in throat, mouth and neck sores. I even developed a strider in my throat due to inflammation and swellness. In September, I went to go see my ENT to go over my most recent Pet-Scan and to do a laryngoscopy of my throats through my nose. Pet-scan results were great and no diseases or tumors in my body. He did perform a CT scan which revealed a lot of extra tissue in my throat. So, he went in again to remove unwanted tissue and any obstructions in airway. I could swallow much better the next day what ever he did. I see him in about another week. But in the meantime, I am fatigued, in pain, swollen, inflamed, etc. I am taking 40mg Presidone a day and Amoxacillon 500mg twice a day. I have a lot of coughing fits and I still feel sores in my throat. I see my Oncologist this Wednesday to go over my progress. My Oncologist did suggest the I go through Hyperbaric Oxygen Therapy if my current treatment for these issues doesn't get better. I feel that I have been through a lot for a person that only had stage 1 cancer of my larynx.

I would appreciate any feedback on my issues With this, and thank you for letting me be in this forum.

Sincerely,

Jeffrey
