Twitch in back - not sure why?

Hi all,
I made a thread recently when I was concerned that my beardie Hawke's back leg was twitching. He was taken to the vet and had blood work done -- those results can be posted if that would help. Basically all looked well aside from a slightly elevated uric acid level. He has been getting significantly more water now to combat that, and overall seems much happier and peppier because of it.
I have not seen that leg twitch again since just prior to his vet visit. However, as of last night I saw a small twitch on his back, beneath the skin on the right side (right when looking at him from above, that is). I've never seen this happen before and haven't been able to find any real threads regarding a twitch like this one. Could someone give me some advice as to what may be causing this? A link to the video of the twitch is below. It was more frequent last night and has since become a little less.

That might just be a random muscle spasm. If it doesn't happen continuously or for a long period of time I wouldn't worry about it too much. Offering extra hydration is good for the elevated uric acid levels.

Yes I was speaking to Tracie through PMs about the uric acid levels so I asked her about the twitch as well and she said the same thing. I'm inclined to think it was just some random + temporary thing at this point, as it seems to have stopped and he's still doing great! Thank you for the added reassurance!
