Welcome @blondie98418. You've come to the right place to learn and get tips from fellow longhaulers. I moved your message to this existing discussion since your primary issues are GI related:
– Covid Recovery: How can I manage GI issues? https://connect.mayoclinic.org/discussion/covid-recovery-and-gi-pain/

I did this so you can read the past posts and connect easily with other members. I also suggest that you browse through the topics in the Post-COVID Recovery group to learn more about how others are managing the other symptoms you also experience, like headaches, anxiety, depression, etc.

Have you been to a post COVID care clinic that specialized in longhaul COVID?
