Infection around rig tube

The last few days it has been a bit sore around the rig tube site.  There is obviously a small infection.  I mentioned it to Nurse Mary she took a swab and had it analysed and matched to various antibiotics.  I forget the name of the bacteria.  Anyway I guess Simon thinks I have had enough antibiotics so I didn't get any.  Mary suggested a dressing, which I tried, but somehow the infection seemed to fester under the dressing and became even more uncomfortable, so yesterday I dispensed with dressing and after I had cleaned it again Nicki sprayed the area with colloidal silver.  (Repeated twice a day) Now it seems to be improving I am happy to report.
