I've had an eyelid bump for years and can't cope anymore, any ideas?

Basically, I can't find a single image or piece of information anywhere online that describes or matches the bump I have, so I'm resorting to forums.

 It's on my upper waterline and appears to just be part of the waterline itself. No fluid, no discolouration, it's not swollen, etc., it's just a bump. I've had it for over a decade and it's been remarked on by various opticians. Quite frankly, it's ugly and I've always been able to feel it, I can see it if I look upwards and I've noticed that it means my right (affected) eye closes less completely than the left (unaffected).

It's uncomfortable and makes me incredibly self-conscious and I've never had a positive doctors experience so I didn't want to go if they just dismiss me as usual.

Thanks for any advice.

Just was told by my dermatologist that it Is benign problem and for me they recommended surgery by an eyelid surgeon.  I intend to do it this summer.  Yesterday, someone told me that biotin can cause it,  Don’t know if that is accurate or not.  Keep me posted.  Good luck.

Thank you!!
