I have read through Oddballs postings which were extremely helpful, but none seem to fit exactly what I have. I have just recently gotten a very deep cough and have gone on antibiotics with no effect. I also have some cuts that are healing very slowly and once they have they become raised and hard. I also have multiple quarter size rashes on my arms where Ive been cleaning tanks and such. Does this sound like a possible aquatic bacterial infection? I have not been around any marine tanks lately just freshwater.
