Hey, I think what the other person was asking was just if there is incents or scented candles burned around him a lot. If and when people clean around the enclosure what is being used and stuff. But if your son is 8 I don't think hes burning candles and stuff in his room. In the pictures on his right side it almost looks bumped out, is it? Or is it just the picture, and if it is when u feel it does it feel hard? If you look at the first 2 pics you can see what I mean. As for being swollen he doesn't look like he is to me, he just almost looks like there is something hard in his side. And when the other member asked if your applying the stuff to water per instructions is because to little is no good but then to much of it wouldn't be good either. Its like the saying I have seen used on here before, sometimes to much of something good can hurt you to.
