Hello,
Since you have history of extremely poor vision, you are suggested to visit an eye specialist and get your vision tested. May be, with a pair of lens you will be able to see better. You will be treated with medicines, eye drops and surgery if required, depending on the pathology detected. You also have
sinus problems and now are experiencing
dizziness you are suggested to get clinically examined by an ENT, get X-ray PNS done to detect any deviation in the
nasal septum that requires correction or other pathology that is causing dizziness.
Blocked sinus may trigger
allergy, cold,
lightheadedness hence causing middle ear disturbances, pressure in the ear gets disturbed causing balance problems and dizziness. Get treated at the earliest, you will be given conservative treatment but may be recommended surgery if required. Since you are dizzy, stay at rest. Avoid doing heavy work and do not drive.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
