What can I do for small blister lumps under my eyes 2 months post surgery? (photo)

Thank you for the photo which shows the "blister lump" on your lower eyelid. This can be one of several things and you require to have your eyelids examined by a skilled oculoplastic surgeon. It can be early keloid scar, inflammation, unlikely to be infection, or an activation of a medical skin condition. It is unusual to get scarring below the lash line but possible. By getting an examination the surgeon can examine the skin better than a photo as they can not only look but also feel the "blister" area, thus gaining more information about it. Then they might be able to offer specific advice and treatment for it.
