Big lump on left side of head

I have this bump on the left side of my skull directly above the top of my ear. I think it is somewhat normal to have a little bump here but it literally feels like an egg shape is coming out the side of my head. It's causing me a lot of uncomfortable pressure and headaches. My doctor diagnosed a cyst on the very top of my head but this feels different. The pressure is almost unbearable. Any help is greatly appreciated. A few weeks ago I was having vision issues but that had gone away since then. I went to the eye doctor and he said my optic nerve was fine.

Hello,
It can be a pilar cyst but it makes sense to get a CT head to rule out other causes also. Pilar cysts manifest as smooth, mobile, asymptomatic swellings, often in the scalp. Overlying hair loss may be noted. The definitive treatment is surgical excision of the cyst. My sincere advice would be to consult a dermatologist.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
