Hello,
Welcome to healthcare magic.
Thank you for your query.

Pineal gland cyst is common in the population.
However, most of the cysts are asymptomatic.
If it is slowly increasing in size, then it may cause headache & sometimes it may cause hydrocephalus (obstruction to the brain fluid pathway).
If it is symptomatic then treatment is needed.
I am sorry to say that surgery (excision of the cyst) is the only treatment option.

Before going to surgery, confirmation of the diagnosis is necessary.
Because these are very rarely symptomatic.
Tension headache & migraine should be excluded, as these are the most common causes of headache.

I hope I have been some help of your query.
Please write if you have any doubt.
Take care.

You would need a neurosurgeon to work with you. As I practice far away from your locality, I am sorry I may not be of much help with referring you to a qualified neurosurgeon.

That being said, pineal cyst is usually asymptomatic and detected incidentally on scans. Therefore there are high possibilities that any of your symptoms - headache, nausea and vertigo may be related to the pineal cyst. You can discuss with your physician to confirm the relations between pineal cyst and your symptoms. If it is indeed symptomatic, you can be referred to a neurosurgeon.

Hope this helped. Let me know if you need clarifications.

Regards
