Hi! Concerning ME/CFS. What we can learn is that some heals spontaneously. This is probably the best hope we have. You often hear about a sudden onset. As for me, one day i woke up and, "shit what is this". We just have to hope for the reverse mechanism. Do you know someone who spontaneously healed to tell about it? It sounds like a long phase-disease. Ordinary flu is for 7 days. ME is 7 years. But when one hear about healing it is just as mysterious as the onset. At least one can read about it on Wiki: "Prognosis A systematic review of 14 studies that described improvement and occupational outcomes of people with CFS found that "the median full recovery rate was 5% (range 0–31%) and the median proportion of patients who improved during follow-up was 39.5% (range 8–63%). Return to work at follow-up ranged from 8 to 30% in the three studies that considered this outcome." .... "In five studies, a worsening of symptoms during the period of follow-up was reported in between 5 and 20% of patients." A good outcome was associated with less fatigue severity at baseline. Other factors were occasionally, but not consistently, related to outcome, including age at onset (5 of 16 studies), and attributing illness to a psychological cause and/or having a sense of control over symptoms (4 of 16 studies). Another review found that children have a better prognosis than adults, with 54–94% having recovered by follow-up compared to less than 10% of adults returning to pre-illness levels of functioning." What does it mean? Hard to understand.
