It’s definitely the daing na bangus. Less than a month after getting downed by either food poisoning or allergy reaction, I get downed again. This time after again eating daing na bangus for lunch. The same symptoms appeared: my pulse started racing, then the throbbing headache, then the fever, and finally red splotches showed up all over my torso, legs, arms, and face. Again I had to make an emergency exit from work to recover at home. But looking at the bright side, at least I’m now sure what causes it. No more of that crap from now on.
UPDATE: It looks like food poisoning since one of the officemates I had lunch with had exactly the same symptoms. I looked up the symptoms my officemate and I suffered from and I got this: scombroid fish poisoning.
Unfortunately, no.
