Feeling unsteady off balance when walking. doc says could be wax build up in ears. what else could it be?

Hard to say: Would need thorough history and an exam. Duration of your issue, history of some trauma, etc. I would see an ENT specialist

With decent exam: not too much else and not much different. On the exam, movement of the eyes associated with moving the head and causing the dizziness shows that the dizziness is when the ears and the eyes are giving different positional signals. An INNER EAR problem then, is the cause. Wax, infection, damage to the ear nerves (often viral..taking months to get better) are the common causes.

Dr Fowler and another doctor agreed

Ambulatory balance: It could be hard wax pressing on your ear drum. That's an easy fix but their are a number of other problems which could be causing it. You need to consult your primary physician for guidance on the diagnosis and treatment of your balance disorder.

Anemia: With your history, unsteadiness could be coming from anemia due to blood loss from heavy menses. Eat iron rich foods such as red meat. See your doctor for a blood test if symptoms continue.
