Wondering if I can get a little help with something. I just went through a lot preparing for a colonoscopy and finally got it done and everything was fine. I was looking forward to an anxiety free period, but instantly I started having this weird pressure in my head. It is like I have a hat in but I don't. I can't shake this feeling. It also sometimes feels like my head is tremoring but it isn't. Any help you can give me would be so appreciated.
