Hi @jcl2018 Welcome to the head and neck group. I have not heard of barorecepter failure due to radiotherapy but I think I will look into that for future reference. This cancer, especially the treatment is the gift that just keeps giving. I'm saddened that this is now happening to you after your past experiences. This issue of course could stem from something else entirely such as the Covid vaccine or just one of those things that goes haywire as we progress through life. Radiation however really does a number on us. Tons of fun.
Anyway, I hope someone here has some insight in this particular area and will pop in soon. In the meantime, welcome.
