How Can Persistent Headaches That Do Not Go Away Even With Medication Be Managed When Everything I See Is Yellow?

Hi, I have been getting headaches every day and no pain meds can control it but lately for the las couple of days I have been waking up freaking out because I see everyone yellow. And after some time it goes away but I see a bit blurry and have been forgetting a lot of things and I m only 27 years old. My husband tells me that I wake up screaming and freaking out because of my vision. Please help me know if this is an emergency. I have 2 kids and can t really get sick.
