I had all that – starting with symptoms identical to a heart attack leading to four days in hospital for extensive checks all of which came out negative (i.e. positive for me!)
Months of breathlessness, lethargy, fatigue, chest pain, muscle pains.
Got checked out for Lyme cos I had had a tick a few months earlier – still negative (i.e. positive for me!)
Eventually got better. Went to GP for final checkup and asked what the hell happened to me.
He said: Best guess is – a viral infection of the peripheral nervous system. He comforted me by telling me if it had been a viral infection of my central nervous system (like meningitis) I would be dead.
Thank God for peripheralness say I
