Hi @nanandalex Welcome to the Head and Neck group. I too was nauseated from the radiation treatments, whether it was from the excessive mucus or actual radiation “poisoning” is unknown. Radiation poisoning is a term used to describe side effects from radiation, common after exposure such as was the case in Japan after the A-bombs were used. Not everyone is susceptible but some of us are.
My sickness occurred roughly five hours after I was zapped for the last four weeks. It was not an issue on the off day weekends and did not persist at the end of radiation treatment. I was prescribed different anti-nausea meds until finally landing on one which worked well. I don’t at this time recall which medication it was that worked for me, but it worked.
I was also short of breath and felt beaten. It took better than six months to get my breath back.
Mind his thyroid levels. Radiotherapy occasionally can bruise or otherwise damage the thyroid, which is located at the base of the neck. If the thyroid stimulating hormone or TSH is out of normal range, this is an indicator of thyroid damage. Any levels near or beyond normal range can make the patient feel all matter of horrible. It’s a simple blood test and one I encourage all neck radiation patients to request.
My thyroid crashed, followed by a return beyond normal output. Investigation revealed one wing bruised and enlarged. A simple daily medication brought the level within normal range, which I managed for more than twenty years. Eventually I “aged out” and presently taking neither thyroid reduction meds nor thyroid replacement meds, which is more common in older folks like me.
Things should only improve from this point on. It does take years. Some issues never resolve in a few patients. In the meantime, courage. Good healing.
