[|Human|] my 4 year old little boy has a bump 1/4 in diameter on the outer edge of his upper left eyelid. It is about 3/16 tall in gets smaller after a night of sleep and then gets bigger as the day goes on. It has been there for three weeks, It is not getting better but not getting worse either. It doesn t seem to bother him what so ever. It looks like a bb under the skin and it is not red or anything. What is it?
[|AI|]  Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint a bump on the outer edge of the upper eyelid of your son seems to be an infection in the oil gland, and it can grow gradually over the days. Other causes of lump on eyelid can be Champion, papilloma, cyst etc. I would suggest you to consult an Ophthalmologist and get evaluated, and he can do a thorough clinical evaluation to rule out the exact cause of the lump and then only the appropriate treatment can be advised. As of now you can do warm compresses over the lump for reducing its size and if it is a style or a Champion it can start regressing in size. The physician can advise you to apply antibiotic ointment over it. If it is a cyst he can do incision and Chat Doctor. . Hope this information helps. Thanks and regards.
