I have had a swelling under my eyelid for about 18 months and if I press in the inner socket of my eye stuff comes out, sometimes it s pure white and sometimes it s a creamy colour and can smell and be quite thick it has also been a clear jelly like substance I can press this stuff out of my eye up to four or five times a day and sometimes my eye can ache a bit deep inside I have tried eye drops or just plain bathing it but it never goes away what is this and what else can I do.
