Scared of brain aneurysm!!

Please help I've been in a lot of pain today in my head it feels like a Thunderclap headache like basically a thunderstorm going on in the front of my head. I'm very nervous and scared because I've been all so nauseous and vomiting and I've heard that can be a sign of an aneurysm. but I literally am at the ER like once a week and have had so many scans done on other parts of my body. I'm scared that if I don't go in something could be wrong or I'm scared that if I do go in I don't want to get another scan for nothing. has anybody else experienced these types of Thunder headaches because apparently Google says the only way you'd have that is if you're having a brain aneurysm!!

You need to understand going for scans  is counterproductive, I am surprised the hospital does not chase you.

You have had the tests you have clear results, your headaches could be stress or Anxiety

No.. the tests have been on other things. For example... a month ago, I had chest pain and thought I had PE, so they scanned my chest. 2 week’s ago I had blood in my stool, so the scanned my stomach and a week ago, I had stomach pain and thought I had a kidney stone, so... they scanned me again. Everything has come back fine... but now it’s my head. Vomiting, headache and head numbness. Yes they should chase me away but there is always that... what if? What do you think? Those thunder headaches scare me... and I’ve been dizzy

I wonder if all those scans... 5 in 3 months... has made me feel sick?
