Mucus

Very common side effect Sophie though I was lucky enough to not have it too badly. Apparently gargling and rinsing with bicarbonate of soda works for many. Some blood isn't surprising and also very common, the damage done by the treatment takes a fair while to heal so if he's coughing and spluttering that would explain it. If the bicarb doesn't work have a word with his team, and hopefully you'll get more replies on here from people who suffered similarly.

Thank you very much! I’ll suggest it to him and see if it helps. 

The only thing I can say is to take it out, not worth the struggle trying to  swallow it.

Hi Sophie

the mucus is a common side effect of all the treatment it’s our bodies way of protecting our throats and mouth , It can take a good few weeks for it to subside , I was given a nebuliser from  the hospital and used it up to 6   times a time it helps thin  the mucus , plus was prescribed carbusistine also to help thin the mucus . Like Ron says spit it out I must have gone through a box of Kleenex a day for weeks  also gargle and rinse mouth with either baking powder or bi carb mouth washes sometime it helps , if his mouth can stand it a little amount of Diet Coke can also ease it.

good luck
