What is the hard lump on the bridge of my nose between my eyes? (photos)

A scan is a requirement! Than see ENT or facial Plastic surgeon. Depending upon there scan dx would than allow surgical options to be discussed.

Thank you for the question and the photos.  Whatever the mass or bump is it should be evaluated by either a plastic surgeon or an ENT doctor.  They will likely want to get an MRI or CT scan.  The mass may be associated with your rhinoplasty but can also be associated with your sinuses or it can be from the skin itself. I hope this helps.All the best,Dr. Remus Repta
