Weird side effect ajovy/atogepant

Something very weird happened to me. I used Ajovy injections for a couple of months on my belly and leg. This led to injection site reactions including red, irritated, painful skin, swelling and rashes. They usually stayed for a couple of weeks. Then I stopped using the injections, and, one month after stopping, started using Atogepant pills. Then THE SAME site reactions on my leg and belly returned. Did this happen to anyone else?
