Outside Fishball and dust?

Just when Jerry's skin was getting better, it flared up again...
This time the suspect is "outside fishballs"
Jerry took 2 from church on Nov 18 Thurs night and Nov 19 Fri morning, his legs started to get weepy.

Then we went to a friend, Sansan's house, came back the eczema seemed to get worst. Maybe it was the crawling around the house. Dust worsened it?

Date started weepy: Nov 20
Suspects: Fishball, dust
