Ongoing fatigue

Hi and welcome. It could be radiation fatigue which can linger for months. It’s worth having your thyroid function tested as well. RT can damage the thyroid and leave your metabolism low. 

Hi I’m now Almost 4 years passed radiotherapy for tonsil cancer and I did have radiation fatigue for quite a good while in fact it’s only the last 15 months that I’ve stopped having a 20 minute power nap at every day for me that was the way I could handle it. It’s like a wave that  hits you. I do have my thyroid checked annually and touch wood it’s fine. I do know many who are now on thyroxine too regulate their thyroid. 
hope thus helps.

I'm around 11 weeks post treatment 2 chemo sessions and 30 radiotherapy sessions. Swallowing muscles still weak so still dependant on Fortisips, dry mouth and minor pain in the mouth and jawline. All of that I can handle like a walk in the park. 

However the fatigue is immense for me as well as frustrating. Some people have it for months others are doing the funky chicken straight after treatment. I'd defiantly ask your GP about if it could be you medication. Otherwise its a case of eating as healthy, drinking enough water, exercise which could  just mean a 20 minute walk(to increase metabolism and energy levels) and make sure that you take time to rest and get some quality sleep.
