This is Dr Basu, experienced InternalMedicine Specialist.
I am here to address your concerns and provide great service.
Your headaches are coming when there is increased metabolic activities like during sex or physical exertion.
This raises the question of brain aneurysm or a tumor.
These conditions are rare but should be considered since your headaches are also not that typical.
Hence, a brain scan like MRI scan is necessary at the least.
You can go to the ER or you can pursue with your doctor whichever is more convenient.
This can very well be migraine headache as common explanation but this should not be assumed without further evaluation.
Please avoid any strenuous activities till further work up.
It was my pleasure to help you today.
