For the last couple of years, I'm having frequent headache targeting only one side of head usually. Also I'm feeling pressure and pain at sinuses also. Recently I took PNS CT scan. Attached is my result. Kindly advise me, if i have to do something or it there is anything serious. I have consulted a doctor who told me that the headache and this sinus pain has got no relation. Also I'm having some visual disturbances also like a light white light appearing in my vision, then seeing specks of light, black dots/images etc. I've consulted an ophthalmologist also who did fundus examination and found no problem. Should i undergo more tests? Kindly advise. Thank you in advance .
