Yesterday: Eye discomfort, redness and this morning swelling of the eyelid and eye stuck shut upon waking.

It appears that the symptoms described are indicative of a bacterial conjunctivitis. A recommended over-the-counter treatment for this condition is Polysporin eye drops. It is important to follow the instructions on the packaging, typically applying one drop to the affected eye four times a day for 5 to 7 days. If the symptoms persist or worsen, it is advised to seek professional medical advice, especially if you experience sensitivity to light, blurry vision, or pain in the eye.
