Hi am 11 years out of treatment and I feel like still whenever I get a bad cold it is so intense. I have gotten a few sinus infections over the years and with this last one I got a terrible cough and lost my voice for over 2 weeks! It’s almost back now but I wondered if it was so severe because of radiation. I feel like it has changed so many things. I too also have the awful hard stiff cramps neck thing too which I was reading about here. I’ve worked with massage therapists and try to do lots of stretches but it always gets so stiff and hard if indeed my do massages and the stretches regularly
