Eye pain is not normal, so don't ignore it! If pain in or around your eyes occurs suddenly or worsens rapidly, see an eye doctor immediately to rule out a serious underlying problem - AllAboutVision.com
A pterygium is a non-cancerous growth of the conjunctiva, which lays over the sclera. In most cases, a pterygium grows from the inner corner of the eye. A pterygium is usually painless, though it can cause irritation to the eye at any stage. The tissue is often triangular, pink and fleshy. Fine blood vessels may be visible.
