I‘m really worried, do I have CFS - PEM?
I had the flu in late January 2026, and I’d basically recovered from it (according to blood tests, my cardiologist, etc.), so I was able to start training again and go back to work (triathlon training and a stressful 60-hour-a-week job). Since I had a major setback in March after two intense training sessions (about 48 hours later), I decided to take a break from training. I also had a few panic attacks (or at least I think they were) during that time. Then, in early April, I quit my job; I felt fine for a week, and then it completely knocked me out. I was just dizzy at home, and after an hour of normal activity (walking, working, housework), I was completely exhausted. Then I felt slightly better. However, this has been going on for 5 weeks straight now, with no noticeable improvement. I have restless sleep, headaches, and dizziness when standing up (now and then). During exertion or activity, the headaches get worse and I get a sore throat.
Yesterday: meditated (20 min), walked for 5 min, and tried a relaxation exercise with lymphatic activation. Afterward, I suddenly experienced extreme muscle weakness and inner restlessness. However, no headaches or sore throat.
I know it’s still very early (5 weeks) for symptoms, but this is really taking a toll on me, especially the exercise intolerance.
Does this sound like PEM/CFS, or do you think it’s more likely some kind of chronic stress from overexertion? My therapist suggested the early stages of burnout, but I still have too much drive for that and don’t feel burned out.
