I am a 22 year old female who is generally healthy. I've had this problem for years and my optometrist has no idea what is wrong. Every time I put glasses on, within minutes, I have this intense, debilitating pressure on the back of my head on the left and right side at the bottom. When I laugh really hard or cry really hard it also gets this pressure. It makes me have to double over and sometime throw up the pain is so intense. I can't wear my glasses for more than 3-5 minutes at a time. I've tried new glasses. Changed the material of the lens and the angles or however they do that stuff. Thinking about getting an MRI/CT scan just to see what is going on but was wondering if anyone has experienced this or knows the possible cause
