Coincidentally, I'm just off the coast of Bornholm, where do they get all the fog
The name brought back painful memories , in the mid 90,s I had a strange chest problem , principally breathing was extremely difficult and painful .
Went to the Doctor who diagnosed "Bornholms Disease "
Apparently it was discovered on or by someone on the island .
It is an infection of the diaphgram .
I was in the south of England
then , so had not the faintest idea how it found my chest !
keep a good lookout for it ......
