Lower Ab pain-11 wks post op ALIF

Asking if anyone else has had deep, dull, burning and firery pain between naval and public bone. It’s worse when lying down. Until now, I’ve had almost no abdominal pain. This started 10 days ago. ER visit showed normal Labs and CT Scan. No fever, no vomiting, mild nausea and normal BM’s. Appt scheduled for Gastro in 2 weeks per ER. But, wondering if this could be related to ALIF.
