Penny H - had 6 weeks of radiotherapy on my vocal cord and struggling with fatigue. How long will it last?

 Hi, I'm new to this group. I had my 6 weeks of Radiotherapy last June on my vocal chord , I've lost alot of my saliva and taste which I can cope with but the fatigue........how long does that go on for ?  I don't know whether it's normal or should I see my GP ?

My thyroid also suffered badly and I'm now on thyroxine but I have regular blood tests to make sure that it's ok.

I'd be grateful if anyone has any thoughts on this
