I've dislocated my kneecap a few times and the near-immediate swelling was much worse than the actual injury. Recovery took a few weeks anyway so easing my discomfort for a couple of hours made no difference.
Our sinuses have shrunk and or airways collapsed far too quickly for evolution to adapt, leaving us highly susceptible to allergies and inflammation. This makes the likelihood of catching a cold or flu much worse. It also makes the healing process longer.
I very much recommend you read Breath by James Nestor if you suffer from allergies. Or at the very least, let chafgpt summarize it for you.
The point is that evolved responses don't always properly account for nuance or proportion. If inflammation evolved for large traumatic injury, it may still be triggered for limited soft tissue injuries but then the response could be disproportionate.
(But aren't joint injuries usually soft-tissue as well? It's the ligaments that get the short shaft.)
