Recently, my right eye has a feeling of tightening from the corner of the eye. When I look at myself in the mirror and then look upwards, I notice the change in appearance of the skin "pulling". If I pull the skin away from the eye, it feels "good" ... but immediately goes back to the tightening feeling.
What causes this sort of thing? Is there a way to stop it from happening?
Background: I have hayfever and have been taking Claritin D to alleviate symptoms of congestion, red and stinging, burning eyes and itching upper mouth. Could the eye tightening be caused by the medicine?
