Hi ms. Kavita, Seems like you are suffering from this problem a long time. Have you checked your eye power? If not please go and check with nearest optical and if prescribe specs, wearing them will relieve you of pain. But if you have already checked vision and its normal, you may have any one of the three: 1. Tension headache: it is due to severe tension and becoming angry. If it is so, you have to controlgetting angry and do relaxation exercises like pranayama thrice a day 2. Lack of sleep: if you are not sleeping regularly, it can also cause headache. Donor see cellphones or see TV before sleeping. 3. Migraine: the doctor prescribed you duzella for this. It is better to take vasograin tablets twice a day after food during headache episodes. Prevention of migraine: 1. Donor drink cool drinks or ice cream 2. If headache comes switch off light and try to sleep 3. Avoid Marsala containing foods and chocolate 4. Donor watch TV, use cellphones, laptops for long times 5. See whether stopping drinking milk reduce the symptoms. Thank you. All the best for quick releif
