yea i would also say its an ulcer

probably best to read this article rather than try to explain.

if you carnt do much till the weekend i would buy some aquarium salt (pets at home should have it (i dont like going there but there open till 8pm so handy for emergency's) and do atleast 1 salt bath per day as this will clean the infection. read up on the net about salt bath's. (do not put salt in the tank)
