hello,
Welcome to HCM.
You have not described your symptoms elaborately, anyway,
causes of headache, chest pain and sinus problems are many but combination of these symptoms, i would suggest to undergo an X
Ray PNS (waters view) and
ophthalmology consultation for
refraction errors. For symptomatic relief you can take a plain paracetamol tablet.
Seeing is always better than assuming so get yourself checked up by an ENT specialists.
Wish you an early recovery. Thanks
