Damn sea ulcers on hands and legs……

I have presently got three big sea ulcers on my right hand and two on my left leg getting deeper each time I surf and ride my moped on the dirt roads back to River’s villa where I am staying. The dust on the roads is full of buffalo, chicken dog and cow traffic and the dust blows straight into the open wounds which have just opened up as a result of being in the sea for a few hours. Regardless of the betadine, iodine, sudacream, guazes and dressings I am using the damn things just keep getting deeper. The swell has been pretty good so staying out of the surf really will be a last resort.. Aghhhhhhhhhh!
