Headache has many causes including migraine, tension headache, sinus infection, post concussive syndrome, and others. Squinting eyes can be do too light sensitivity, which can accompany certain types of headache but may be related to other conditions. Because these symptoms could be related to different medical conditions, it is important to describe all your symptoms to your health care provider to determine the cause.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Eyeglasses, Sunglasses, and Magnifiers
Nonprescription eyeglasses are available over the counter (OTC) and are typically used by people who can no longer read fine print. OTC trifocals are helpful for those who require multiple distances or focal lengths for near and intermediate tasks. OTC sunglasses should offer 100% protection from the sun's UVA and UVB rays. OTC magnifying glasses are useful for viewing tiny objects or fine print.
A tension headache s one of the most common types of headaches, and the exact cause is not known. Factors that may contribute to tension or stress headaches are lack of sleep, increased stress (referred to as a stress headache), skipping meals, dehydration, medical diseases or conditions, anxiety, or changes at home, work, or school. Treatment of tension headaches include prescription and OTC medications, stress management, and treating any underlying illness or condition.
Presbyopia is the age-related loss of the ability to focus on objects that are close up. The condition generally affects people over 45 years of age and causes blurred vision, headaches, and the need to hold reading material at arm's length. Presbyopia cannot be cured. Prescription contact lenses and glasses can help those who have presbyopia to see more clearly.
Meningitis is inflammation of the membranes that cover the spinal cord and brain. Symptoms include fever, headache, and a stiff neck. Treatment of meningitis depends upon the cause of the infection and may include antibiotics or antiviral medications.
