Hello, I am a 22 year old female and I am having very bad headaches and eye aches 24/7. It feels as though my head is swelled with pressure and I have a flickering /shimmering spot of light in my central vision. I went the hospital and got an Mri and ct and everything came back good. The doctor told me it was a neuro problem since I was seeing the flickering in both eyes. I have an appointment with an eye doctor next week and a neurologist the week after. It's driving me crazy. I am also having sensitivity to bright light.
