Weird how some Axie's take it better then others. I have this little runt of a thing who got her leg chewed on by a bigger axie. It ended up doing the same thing with bloating and falling off. She seemed quite okay with everything. I gave her a few salt baths here and there. No fridge cooling or medications. She now has her toes growing back, took a while though. Actually I should be saying she/he. I think it's a she. You should just stick with one plan and keep to it or Daddy will get more stressed. Don't use any medications if you can. Otherwise the constant change in water will probably cause more damage then it should. That's my advice.
If you're trying to take a photo, make sure you're not creating a shadow over him, or the other way around with light. That might be what sends him crazy. Makes my precious babies (1yr) go crazy when there's light one second then shadow the next!
