Ok, I think I found out what it is.
Cloacaliths
Dehydration of captive snakes (especially if long-standing) may result in drying out of urinary excretions. When this occurs, uric acid "stones" tend to form within the cloaca ("cloacoliths"). Their presence in this location prevents expulsion of urinary waste and feces (
constipation), which creates serious illness. Dehydration is a sign of disease and not a disease in itself, so it becomes the veterinarian's task to determine the underlying problem that caused the dehydration. Cloacoliths can usually be manually expelled with patience and the help of mineral oil enemas. This procedure should only be attempted by an experienced veterinarian.
I will try and take my snake to the veternarian tomorrow. I just hope they can fix it because he is kind of a small snake.
