I'd suggest almost all of the PVS recoveries are spontaneous in nature, based on luck/natural recovery.
Yes - agree.
I put my PVFS recovery down to my inability to move much, luck, caution and natural recovery:
My first experience of ‘energy limiting chronic illness’ was June 2001
Described by GP on sick notes as Post Viral Fatigue (and later with added - ‘Syndrome‘).
Signed off for 8 months before a medically overseen (very slow) graduated return to work.
Never managed to achieve full time hours ever again, dropped from 37 to 22 hours pw
It was very definitely the result of a severe virus - sudden onset, very flu-like but also extreme gastric problems.
From notes I still have from the time (unfortunately I didn’t keep all of them), I did suffer with PEM, severe neck and shoulder pains, weak as a kitten, breathlessness (my oft told tale of panting as a result of just folding up a basket of tumble dried items), digestion and gastric problems, amongst other symptoms
Housebound. No driving. Parents took me to medical appts. Husband worked FT, looked after children, did shopping,cooking, cleaning, everything.
Month 6 (Nov) Appt with Consultant and I was manually checked (No scans) to discount MS, before being diagnosed with PVFS.
OK - now please don’t shoot me down, but also - I was prescribed a 10mg dose of SSRI (which I was told was ‘very small’ and did not imply that he thought I was depressed.)
Also Nov, visit from Senior Personnel Manager to home to discuss my work situation with Father (a retired Chief Admin Officer with Local Government) in attendance.
Improvements in energy Dec & Jan.
End Jan 2002, visited work & graduated return to work was agreed but I was still unable to improve as quickly as they planned and so transferred to part time working by April (?) with always Wednesdays as a non working day.
Feb 2002, met Senior Personnel Manager at work and she ‘didn’t recognise me’ as I looked so much better.
I describe myself as eventually feeling 90-95% well by 2005, and thereafter, until sudden event 2013 changed it all again.
