Why does my leopard gecko have a bubble or lump under its skin?

Updated On September 23rd, 2025

Pet's info: Reptile | Lizard | Male | unneutered

My (male?) leopard gecko has what appears to be a bubble near its front right arm. I poked it with my finger to see if it was solid and it move, I poked it again and it moved back to over the arm again (on the shoulder). I think it is ether an air or fluid bubble under the skin, I do not know why it was there or how long it has been there, my gecko does not appear to have any other signs of illness.

Thanks for reaching out about your gecko. Could it be a blister from a heat lamp? check heat lamps and how close your gecko can get to them (i.e. basking site on a branch). Maybe place a thermometer at that spot to check. Infections can also cause some blistering. If persists, a veterinary visit is recommended. Good luck.
