 [ Symptoms ] i am concerned about my elevated blood pressure [ Disease ] we do not know exactly what causes migraine but it is unlikely your situation would trigger one further a migraine would not cause irritation to your eye since an eye doctor has told you the eye is fine my own guess would be that the eyelash caused such severe irritation to your eyeball that the nerves there simply will not settle down this is a not uncommon event with nerves in all areas of the body if this is indeed the cause of your ongoing sensation of eye irritation then the good news is it should calm down on its own eventually in the meantime you could try using soothing saline drops frequently for awhile to keep the tissue nice and moist as it should be this may help the nerve endings settle down wishing you well
