Common Causes of Left-Sided Headaches
There are several frequent triggers for headaches on the left side. One notable factor is stress or tension, which can often present as a feeling of pressure or a tight band encircling the head. Another contributing factor is eye strain; extended periods of staring at screens or reading without taking breaks may lead to headaches on the left side due to fatigue in the eyes.
