Early in the summer I had a synthetic corticosteroid injection (Kenalog: Triamcinolone acetonide) for joint pain. To my surprise, I no longer experience the same lymph node pain and flu-like feeling on exertion. As a result I have an increased capacity for activity. It's been several months now and I am still experiencing this partial remission. Has anyone experienced something similar, or know any more that might help me understand? My ME also improved after I stopped my HRT medication.
