Headache with pain in sinus area. Quick.

For the past couple of months, I was having frequent headaches accompanied by pressure and pain at sinuses. Occasionally I was having a kine of pale yellow discharge also from nose. Recently I consulted an ENT specialist who advised me to go for a PNS CT scan which i took already and showed him. I was able to show him the films only because the result wasn't available that time. He told me that there is nothing to worry and the headache I'm having is of vascular type and has got no connection with my sinus. He prescribed a beta blocker for the headache along with an antibiotic for sinus pain. But unfortunately I'm still having the same problem. Due to outbreak of corona, I'm not able to go and visit him again. I'm attaching the PNS CT scan result also for your reference. Can anybody help me with this by advising if there is anything serious mentioned in the result or if I've to do something really quick. Thank you in advance.
