Positives

• A Long COVID patient reported that after seven days of very low-dose prednisone (5 mg once daily), her muscle aches improved by 90%, energy improved noticeably, and post-exertional fatigue was much better Mayo Clinic Connect.
  
  
• A patient seeing an immunologist who specializes in PASC described a short tapering low dose of methylprednisolone as “working like turning an engine switch to on” Mayo Clinic Connect.
  
  
• A patient with a year of post-COVID GI symptoms incidentally took 20 mg prednisone three times daily for a week (for an unrelated back issue) and reported the GI symptoms disappeared completely Mayo Clinic Connect.
  
  

Negatives

• One Long COVID patient experienced blood pressure spikes to 190/100-210/110 on day 3 of a methylprednisolone course, illustrating that response is not uniform Mayo Clinic Connect.
  
  

Hurdles & Side Effects

• One Long COVID patient on prednisone described “powerful fatigue and insomnia” along with weight gain and thyroid issues, while another reported irritability and trouble sleeping that lingered for weeks after stopping Mayo Clinic Connect.
• One patient on a Medrol Pak (the standard tapering pack) ended up in the ER with blood pressure spiking to 210/110, a reminder that even short bursts can shove blood sugar and blood pressure up and that you cannot stop cold turkey without risking adrenal crisis Mayo Clinic Connect.
