Is it possible to replicate symptoms of certain illness using chemicals...

[Bella]

...like in sci-fi movies? to induce symptoms such as fake temporary inflammation or fake fever using chemical

If you're inducing inflammation it wouldn't be fake. Injecting your arm with someones diarrhea for example will cause a major inflammatory response in that injection site and in your body. Not a smart thing to do! I know diarrhea is a gross example but inducing an inflammatory response is neither cool nor painless or fake. You could die!

Sort of... Except that in real life, the symptoms are real, although they can be cleared up relatively quickly with an 'antidote', or just time.
