Sick Baby Bearded Dragon

Question
I would appreciate any advice on what to do right now.
We bought a baby bearded dragon (5 inches long) about 2 weeks ago.  It's always been very frisky and is growing quickly.
Today it is suddenly -acting lethargic,
-not moving it's back legs at all,
-has a puffy/swollen slightly pink vent,
-every so often raises head high, puffs out throat, opens mouth, sticks tongue out & swallows big 2 or 3 times.
Last night I gave it some small medium crickets for the first time ever because the store has been totally out of small crickets for about a day and a half and it will only eat crickets...(we can't get it to eat anything else).  I don't know if this has anything to do with the problem for sure or not. Today, Spike (our beardie) DID poop a large poop earlier in the day if that's any help answering this question.
So far I have tried what I found on an ER reptile site which was...
-Soaking in warm water for ten minutes & gently rubbing belly from behind front legs down to above vent.
-Gave 2 drops of olive oil with dropper.
-Gave one drop of diluted pedialyte.
I JUST did these things as I found them on an ER reptile site, but not sure if they will work and am very worried! Please help!!

Answer
Hi Molly,

The sudden onset of the paralysis along with the other symptoms does suggest that it is due to an overly large food item. Sorry...... I hate to add guilt to an already worried dragon "mom".

The steps you have taken are excellent and exactly what I would have suggested. In fact, I really don't have much more to add other then best wishes and hope.
The poop is a very good sign and beardeds certainly do recover from this problem although the interim period is very scary.

Appropriate body temperature becomes critical in this situation. If he remains cool the enzymes and bacteria that will help to break down that food mass are less effective as are the muscles that move it along. It becomes a tricky situation when the animal is immobile and not able to move about to regulate their body temp. You may need to move him into the warmer end (if he cannot) and out again for rotating periods. I would continue with the other steps as well, hydration is very important at this stage. I would not suggest trying to feed him any type of food (even with a dropper) until you see improvement. Good luck.
