A week ago I noticed small bumps under my beardie's scales that have a yellowish tint. When I hold them up to the light, they seem translucent like there is fluid underneath but it is not an open wound. I accidentally touched his back and he recoiled at contact like touching the bumps is painful for him. They are located along his spine and on one leg. Other than this concern, he is defecating and eating as normal.

Can anyone please give me some advice if they have seen this and guide me on what to do? I would greatly appreciate it
