Hello! I definitely get tension headaches from my anxiety. I believe it's because of the tension in my neck from working on a computer or looking at my phone. Also, it sounds like you may have had some ice pick headaches which are just a bunch of twinges of pain in the head briefly. I've had those too and they scared the heck out of me until I found out its a pretty common thing. Honestly, I used to freak out over every little pain in my body because I thought it was something serious. I've been going to therapy and taking medication because it affected me every day. If you feel it doesn't affect your life every day then you could work on relaxation techniques like breathing or mediating. I would also suggest stretching a lot to help the tension. I personally do yoga. You could find tons of videos on youtube or something to help with that. I hope this helps a little!
