Thankyou John, It got larger and redder adn began weeping a coloured liquid so I called an emergency doctor. He has been prescribed drops for a type of conjunctivitis, unfortunately this affected a small stye and its the stye that has become infected. Thankyou though!
It doesn't sound that urgent. It may be any number of things mostly not serious such as sebaceous cyst. Better get in line to try and see an Eye MD
