Thank you very much for your detailed and helpful reply — I really appreciate you taking the time, especially on this sensitive topic. My vaccination was in September 2021 at Bumrungrad. I went from being completely healthy and working out 2+ hours a day with no issues at all, to developing severe symptoms just a few days later. I’ve been mostly bedridden ever since . The sudden collapse and ongoing exercise intolerance, profound fatigue, and other symptoms have been life-destroying and feel almost identical to severe ME/CFS. This has been an incredibly difficult, painful, and isolating experience for the past years. I’ve connected with many others worldwide in the exact same situation after their Covid shots, and unfortunately very few have seen meaningful recovery. I’ll reach out to Dr. Hiroshi Chantaphakul at Bumrungrad and bring all my test results. Thanks again for the clear guidance — it means a lot.
