Help!

I was holding my ball python today, and saw that from his vent and three inches up the skin is a dark blue color, right at the vent there is something hard and white. He hasn't gone to the bathroom in a while, and he normally goes about once a week (its been almost two). The skin is very tight were it is blue and is very sensitive... I took a pic but you can't see anything... Anyone have a clue what this could be? Or, any advice what to do.?

Try giving him a soak in a tub of tepid (room temperature) water or just ever so slightly warmer than room temp. The water doesn't need to be deep like a swimming pool...just so that it's about halfway up his sides. Let him swim around in that for a bit and see if it helps him "go."

Thank You.!

Almost immediatly after I put him in and he swam around a lot, he went. Thanks again. :D

:) Glad to hear it all worked out well.
