Reaction to radiotherapy

I would like to know if anyone has had a reaction to radiotherapy that results in feeling nauseous. I have had 12 of 20 sessions and for the past week have felt very nauseous and yesterday I could not keep any food down. I had a review and prescribed anti sickness tablets. I was advised that it was not a common side effect but don’t think a “bug” would last this long. Thanks. 

Hi Gilley
I don’t think it’s common, however it can happen. I felt abit nauseous round about half way through, but for me it was more fatigue related. Hopefully things will improve for you over the next week. Try to keep your fluid levels up xx
