Hello 3 years ago I found cancer in the lymph nodes on the left side of by neck. I was diagnosed with Squamous cell cancer they gave me 8 weeks of radiation and 2 sessions of chemotherapy. I had all the normal post stuff but now just recently I have nerve damage from scar tissue in my neck. This has affected my voice ,swallowing, eating, and my speech . I have been told this is permanent and the only thing I ca do is hyperbaric oxygen treatments to stop it where it s at. Is this true? Is any thing else I can do? A
