My 5 year old son has a swollen lymph node in the right side of his neck which is very painful for him. We took him to the doctor as it got bigger and had a red rash around it. The medicine they gave us seemed to work as the following day he was feeling a little better. Although now he is eating as he wasnt for the first 3 days and now when i give him the medicne he throws up everything and we keep trying and he just cant seem to keep it down. He has very blood shot eyes and the doctor couldnt tell us why the lymph node was swollen. If he cant keep the medicine down is they anything else i can do to help him or to help heal his neck? Thankyou!
