Not sure if my onset could be described as sudden or not - over 2 winters had worst flu ever - lasted 10 weeks but recovered - then the next year woke up one day with severe weakness, chills, shortness of breath, muscle pain. Since then periods of relapse and remission - 8 year remission in 1990s.
Now at my worst - bedridden for one year - all over severe pain, severe weakness (can only walk about 20 yards), chills, sweating, painful glands, stabbing pain behind eyes, nausea, dizziness, vertigo, severe flu-like malaise. Mostly bedridden, symptoms fluctuate randomly.
Borrelia and babesia diagnosis 2008, no MCS, no OI, very little cognitive dysfunction. EBV positive for the first time a few months after taking LDN.
I posted a link to an article earlier in this thread which suggested that LDN was more effective with those with a high ESR. Mine is low, at 4.
Still waiting for XMRV home draw.
Did badly on LDN even though only got up to 1.5mg. Main problem was increase in pain.
