Thank you for posting your query.
There is no connection between watering of eyes and migraine
Migraine is a chronic disease and needs long-term treatment.
If you get more than two episodes of headache in a month, you should start preventive medications, such as beta blockers, flunarizine
Frequent intake of pain killers may have adverse effects on kidneys and liver
, and may cause gastritis
, so, you should limit them to 10-15 maximum in a month. If you use preventive medications, the need to take pain killers would also reduce.
Wishing you good health,
