fluid buildup under skin

[Albert Clark]

My bp has an area where there is fluid buildup under her skin. Her skin is stretched out and if I move her the fluid moves around in this pocket of sorts. I have no idea what this is. Its almost like a blister. The fluid looks pinkish in the sunlight. Please help

Wow! Need a picture of the whole animal and the affected areas. Include a description of the enclosure with your husbandry numbers and a pic of the enclosure would be helpful. Stay in peace and not pieces.
