Oh gosh, @ilean. You are going through a lot. I hope you have better luck being seen at Baylor. As you can see from the long wait times and lack of appointment availability, hospitals across the nation are really strapped. If you were seeking an appointment at Mayo Clinic's Post-COVID Care Clinic, the denial is likely due to capacity limits. There is simply more demand for appointments that availability. COVID has wreaked havoc on the health care system.

You've mentioned both GI and heart issues related to post COVID. You may wish to join these discussions:
