Hi,
Thank you for posting your query.
I have noted your symptoms. These are most likely to be due to migraines. Migraine can cause
headaches along with
dizziness.
The bumps on the scalp are not related to your symptoms and are most likely
lipoma or sebaceous cyst (a clinical examination could confirm the diagnosis).
Fo relief of symptoms, you could take
ibuprofen for headache and
betahistine for dizziness.
I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
Wishing you good health,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
