I might be going a little crazy but I swear I can't find the edit button this time. Sorry for the double post.

Anyway, a little update: fearing impaction, i let him soak in warm water for about 10 minutes (until the water got cold). I figured even if it doesn't help, it wouldn't hurt. The frog didn't mind, he sat there rather peacefully looking around until he fell asleep again. After the water cooled off, I heated up some more and gave him a second bath. This time he perked up a little bit, stayed alert and watched some youtube videos with me. After I poured out the water and lifted him up with the wet paper towel, I got a chance to look at his underside and it looks more normal now --- still pink but not so much red anymore. Another thing I noticed was that the area around the cloaca (that looks like a T) was reddened and appeared...I don't want to say swollen, but enlarged somehow. Maybe it means that he was trying to pass, or is about to soon? Anyway, I put him back into the tupperware and kept it on my desk as I worked for a little while. He sat still (awake) for about 5 minutes, then started shifting around a bit, then eventually crawled over the edge of the tupperware and into my lap, and hid in a fold of the blanket that was over my shoulders. I assumed this meant he wanted privacy, and put him back in his tank.
Long story short, I think he's doing a little better...Sorry if I describe everything in obsessive detail, I'm just a bit worried.
