I had radiation alone. Radiation can cause sickness, dry mouth, no taste, low WBC, RBC, anemia, fatigue, and many others that are likley and unlikely, compounded by any pain, nausea meds, canned feedings. Everyone is different, but would expect some type of sickness or ailment, and It also depends where radiated, the dosage amount, duration. Being a young age, your recovery is quicker, treatments are tolerated better than someone older. Good luck.
