edit: another thing I wanna state is that after the activity I would have PEM the day after that lasts less than 24 hours, then be normal again and feel normal for a period that can last up to a month, and then suddenly (somewhere between 20-30 days after the activity) I get into that severe crash that could last days or months, which is unusual compared to what I heard here where people would get the PEM and stay in the crash since or smth
I've had ME/CFS since 2020, and I would describe my illness as dramatically fluctuating. I could spend months mild/moderate, then relapse into being severe/very severe and bedbound for months, then mild/moderate again and so on
I was very severe for months until April 2024. I that period I would crash from the littlest thing. After having a painful tooth extracted (followed by a wel of a painful dry socket), I improved and became mild/moderate again until december 2025. I was able to work from home for about a year without major crashes, and I even traveled to my vacation home in May/June 2025 and it didnt make me get worse. I stopped working around august 2025 so, in hope that stopping work could help me get even better.
In early December 2025, I had to walk a long distance while visiting my aunt. I had PEM the next day but resolved within 24 hours and I actually felt fine for about a month afterward, but then I relapsed into being bedbound again in the second week of January. I stayed in a very severe state (that at times seemed to be getting worse and worse) until late April 2026, when I suddenly started improving again.
Since May, I've had shortness of breath episodes, that turned out to be anxiety-related. I was able to control and stop these episodes. also I suffer from significant insomnia, largely driven by depression and anxiety. but on days when I sleep well, I would feel mild/moderate and well. and no longer bedbound.
My depression became so severe that I could barely sleep, and in June I was awake for almost two days because of it. from june 20 to june 22. That day was one of the scariest days in my whole life.
I recently spent three weeks at my vacation home by the sea because I desperately needed a change of environment for my mental health. during those 3 weeks I mostly rested indoors and only went to the beach twice. Each of those times 1 week apart. The beach is in the same street as my vacation home, and a beach buggy would take my from my doorstep and stop me at the beach so I didnt walk. The trip helped my depression a lot.
However, I came home today and read a comment here from a patient suggesting that crashes may improve several times, but eventually one similar crash can become permanent and you never recover from it. That terrified me because my history of recovering from severe relapses after months was what gave me the confidence to take this trip in the first place. I can’t undo this trip now…
I know nobody can predict the future, but I wanted to ask:
- Has anyone else had a similarly fluctuating course over several years?
- Do we know whether the likelihood of recovering from a crash depends on the individual, rather than there being an inevitable point where everyone stops recovering?
- Is it possible that some people who never recover from a severe crash are in situations where they can't rest adequately (for example, they have to keep working, have no caregivers, or must do all their own household tasks), or have other conditions affecting their recovery? Or is there simply no way to know why some people recover from bad crashes and others don't?
- Last April I stopped eating white bread and milk and eggs, could that have helped me get out of the crash? or is it unrelated?
- I had a terrifying symptom last march for a while where I felt like to energy to move my hands and arms, this also happened to me in October 2023 and both times where inmediately after using a mouthwash, and were the only times in my life that I used that mouthwash. could be related or definitely not?
I'm not trying to suggest that people who don't recover did anything wrong or didn't rest enough. I know many people pace extremely well and still remain severely ill. I'm just wondering whether researchers or patients have any insight into why outcomes after crashes seem to differ so much.
TL;DR: My ME/CFS has fluctuated dramatically since 2020, with multiple severe relapses followed by significant improvement. I recently took a quiet trip that helped my depression, but afterward I read that one crash can eventually become permanent, and now I'm terrified. Does anyone else have a relapsing-remitting pattern, and do we know why some people recover from severe crashes while others don't.
