sunshine,try this,,,get a water pick,,,,,a can of spray disinfectant from a food store,,one with a wide range of bactericide,and,anti mold,antifungal properties,, not as bad as keloggs pop tarts,which have additives,dyes,coloring that kids scarf up by the millions,,,in a four ounce glass of hot water,spray some disinfectant,like a couple 3 second sprays,rinse for 2 minutes,,spit it out,,,do it again,,this you try if no dr is available,,,,,,,I used this method on a 2 month camping trip in canada
after a tooth extraction with residual infection,it worked
you can also rinse with hot salt water,,,,,or pouring a capsule,or grinding up a tablet of antibiotic
into warm water to swish around,and gargle with,be sure not to swallow the god awful stuff .
the guy you saw perhaps missed a site of secondary infection,or the wound is just draining as it should
