[As an addendum to WWX and also anyone else in the vicinity:]

I would say it's not caused by magic, but is exasperated by it. You must have ingested or more likely inhaled something orally; you have discoloration on your tongue and it is also rough textured and dry. There are other signs of dehydration, including shaking, sweating, and a general pallor.

Interestingly I found no signs of injections, cuts, or contact through the skin or other entryway into the body besides the mouth. Your lungs are currently in bad shape [the "obviously" that comes from Changsheng is brushed off] and your heartrate is very elevated, so I would take it easy for now.
