It is painful ophthalmoplegia, requires evaluation
Welcome to health care magic.
I am Dr. Dadapeer K, an ophthalmologist and I answer health problems related to eye.
It seems from the history that your husband is having headache associated with drooping of the eyelids and double vision
probably because of limitation of extraocular movements.
These symptoms indicate neurological problems and require examination by a neurologist
to find out the underlying cause.
The common causes to be ruled out are neurologic migraine
and other conditions causing painful oohthalmoplegia like nerve
Hence I advice you to get neurological examination by consulting a neurologist.
Hope I have answered your question and the information is helpful to you.
