Sick from taking worn antibiotics?

[Kitrix 5]

My vision was slightly blurry so I took some pristine vitamins, pristine pain killers and tried some worn antibiotics; however, after consuming the antibiotics, my status became sick... I don't think it was a delayed sick message from the vision since I had been playing for at least 30 minutes with this blurry vision without being "sick." Any clues as to why and how to cure it?

You get a green sick status from taking antibiotics. This means you are actually getting better at the moment. Remember: status symbols will only appear if a status is changed. So if you are sick at the moment and you got no status symbol, it will then appear if you take antibiotics and change the status (healing)
