<s>[INST] I have a lump just down from my bottom eye lid and it is very sore and tender to the touch... My whole left eye looks like I have been punched... But I get this lump quite a lot and then it disappears im just wondering if anybody has a clue to what it is... [/INST] Hello!Thank you for the query.If this lump is in the area where the eye meets the nose, tear duct inflammation is the most probable reason(called Dacryocystitis). Due to such inflammation,  tears sac gets obstructed and give a kind of lump under the eye.I suggest you to consult eye-doctor with this issue.Hope this will help.Regards. </s>
