Hi, my dad was diagnosed with throat cancer, and has just undergone radiotherapy 5 days a week for 6 weeks and chemotherapy 1 day per week for 6 weeks running along side each other

We had his six week post check at the hospital, and everything was fine however my dad has got lots of aches and pains throughout his body and a dry throat

Is this the side effects of the treatment? 

thank you 

Kay
