Why didn’t anyone warn me about the pain from activating the chain

I got my chain activated for my palatal impacted canine and it has been the worse tooth pain the past 3 days. I also got a massive headache that would not go away. In the past 6 months of my braces journey, I have not needed to take any pain killers til now 🥲 I felt like I never saw anyone mentioned it hurt that bad so I wasn’t expecting it. Anyone have a similar experience? 😩🥲 and when you go for your next appointment and they tighten the chain again, does it hurt as bad every time? Trying to be prepared this time 😅
