Dear sir / madam, Thanks for referring !! I completely understand your concern and your pain which has effected your well being. From your symptoms it appears to me that it may be a case of sinusitis or migraine. If I had a patient with these symptoms I would have examined features like 1)vision power as defective vision leads to headache. 2) checked his blood pressure, sometimes high blood pressure is a cause. 3) tenderness over cheek bones when applied pressure, this will indicate sinusitis. 4) light flashes, radiating pain to ear, back of head, one sided headache.these are seen in migraine, mostly due to some triggering factors like sunlight, sounds etc. Treatment: - i suggest you to do steam inhalation thrice a day , you can add effervescents in it. -avoid cold food items - doing breathing exercises from yoga have helped lot of my patients. You can visit a ENT specialist if desired. In your case we can have a x ray skull done to rule out other causes. You can get prescribed analgesic drugs like paracetamol . Kindly see that you maintain a chart of drugs for follow up reference. You shall be fine sir/madam. Thanks for referral. contact me for further queries. with best regards Dr.Suhas Chauhan
