First SCIG infusion

So I just had my first infusion today. Overall, the side effects haven’t been bad at all. I took Benadryl and ibuprofen before the infusion. I had a couple of side effects. Headache, fatigue lots of tenderness in the abdomen and probably the worst symptom out of them. All is really bad bodyaches. I take Hizentra . Anyone have any tips or tricks on how to help the side effects thank you.
