" For every action, there is an equal and opposite reaction" Newton's 3rd law of motion."

In view of above we can either interpret action (disease symptom) or reaction (defence symptoms) making both valid. It is quite valid that we interpret insect bite causing pain or pain resuting from insect bite. Still, we have to recognise "causing agent" not just pain, to treat accordingly.
