I had a pressure headache complaint on the left side of head, behind parallel to the top of the left year. from a few days. And a dr. had suggested MRV. My MRV report comment says- No obvious venous thrombosis seen, No significant abnormalities in brain, and  Hypoplastic left transverse and sigmoid sinus noted. I wish to know what it means. as the dr. said everything is normal. I also did an IOP, my eye pressure is a bit on the higher side can the headache be because of the eye? Please suggest
