lump on bearded dragons head

Question
My bearded has a lump on the right back side of his head.  It is not discolored and he is acting normal. I noticed that it has gotten larger. It is the size of a small marble.

Answer
Hello Wendy, this sounds like something you should take him to the vet for. It could be serious and need medication. Most bumps like you are describing will not go away on their own and need to be drained or prescribed medication. Talk to your vet about it and they will tell you what it is. Sorry I don't have more experience in this area.

Good luck and I hope its nothing serious
