I Dr. Rynne, I Have A Hx Of Sebaceous Cysts

I Dr. Rynne, I have a hx of sebaceous cysts else where on my body. 6 weeks ago, while at dinner I felt a raised lump forming on the inside of my lower lip, felt like liquid from the touch (cyst looking) and since has hardened a bit, no pain. Has remained the same size and feels very similar to the other sebaceous cysts I have had else where on my body.
