There are a number of causes of dizziness, so it doesn’t necessarily have to be melanoma-related. For example, stress, blood pressure issues, not eating right, blood sugar issues, certain medications, etc., can also cause dizziness. You might want to pay a visit to your primary doc to get to the bottom of this and get yourself back on track. The last thing you need is to have a fall as a result of the dizziness.
I had a full LND done and had no issues with dizziness after the surgery.
