Welcome to HCM,
You have recently suffered a viral infection and now improving, your headache or pressure in head may be a part of viral fever
and should go away in few days and even a paracetamol
Other thing you need is correction of refrective error if you have started wearing contact lenses recently it will take some time to adjust but problem is persisting then you must check with your Opthalmologist to see that power is correct for your eyes.
You can give intermittant rest to eyes and see if it helps.
Please take care.
Best of luck.
