HI, thanks for using healthcare magic Enlarged lymph nodes are normally as a result of infection or inflammation in the surrounding areas. They can also become enlarged if the nodes themselves are infected or in malignant conditions. A full blood count and ESR (checks for inflammation) would be able to determine if infection, infection or other serious conditions are present. It would be best to be reviewed by your doctor. Dizziness can be due to different possible causes such as conditions of the inner ear, low blood pressure, inadequate fluids, side effect of medication. An ENT doctor or neurologist may be helpful to determining the cause for your dizziness. I hope this helps
