Hi,
Thank you for posting your query.
First of all, I would like to reassure you that there is no need to worry about your symptoms, as they do not suggest any serious illness.
Clinical examination, as well as ENT and dental surgeon have not found any thing. This is a good news.
The bone
cyst at the back of head would not lead to pain in the right side of head.
The most likely cause of your headache could be
migraine or muscle
tension headache. Please
consult a neurologist for confirmation of diagnosis and initiation of treatment.
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)
