Harry,
Has your local medical officer considered organisms like _Erysipelothrix
rhusiopathiae_ (often associated with crustacea) or _Mycobacterium
marinum_ (a marine bacterium that requires very special growth
conditions, your LMO has to notify the laboratory of the possibility). 
The usual marine bacteria we immediately think of include _Vibrio
vulnificus_, _V. parahaemolyticus_ (this usually causes diarrhoea) and
other _Vibrio_ species.  If you do any freshwater stuff, we'd also
consider _Aeromonas_ species.  These however, are usually more acute and
cause more fulminating infection.  Occasionally they even kill.  It's
hard to say without examining you, which outlines one of the dangers of
an indirect diagnosis.

Of cause you might just have a routine run of the mill microorganism
like a _Staphylococcus aureus_ or other _Staphylococcus_ species causing
a low grade osteomyelitis.

Get your LMO to refer you to an Infectious Diseases physician who may
suggest a surgeon see you to get a biopsy.

Let me know how things work out.

Gary
