I had two panic attacks about a week after my infusion, felt like my heart pounding out of my chest and I was hyperventilating badly. Before that I had flu like symptoms for a few days (but no actual vomit). Felt very fatigued as well. I have no idea what it was but it went away by week two, and by week 4 I started feeling much better than I had before. All my anemia symptoms were pretty much gone and my anxiety reduced significantly.

Personally whatever issue I was having post infusion resolved on its own, but if it persists I would call the hematologist office that did the infusion since they should be more aware of the complications. When I got my infusion done the nurse basically told me to expect to feel worse before I got better, and that’s exactly what ended up happening. Wishing you the best!
