I Went To The Doctor For Swollen Lymph Nodes And

I went to the doctor for swollen lymph nodes and slight pain in my right ear, I also have dizziness (not vertigo) daily. I was prescribed amoxicillin but I stopped after a few days, went back to taking it and then stopped again because it made me feel ill. I went back to the doctor and I was told to just drink lots of water. I've been drinking lots of water and nothing is helping. Any advice?
