In Feb 2006 - I was diagnosed w/ nasopharyngeal carcinoma Stage IV, and commenced treatment in Apr 2006 - with 35 rounds of radiation, together with 4 rounds of chemo (body not able to handle all 6).
In mid 2020 - I find that I had speech issues - with slurring and not able to form words, and at same time - I had difficulty in swallowing. It was then that I was diagnosed with with severe neck fibrosis, with dysphagia and dysarthria -- late effects of radiation.
I have been doing my best to do dysphagia exercises, and going for physiotherapy treatments - in the hope that this will avoid me having to have a feeding tube for intake of nutrition (as advised by my oncologist he has cancer survivors who have feeding tube inserted).
I was not aware of Botox and/or steroid injections - but this is something I would like to look into.
