Just found this in a Google search.
I am suffering similar syptoms. About six weeks ago I went on antibiotics for a week, having a badly infected finger, which upset my stomach a bit. The following Friday on holiday I had quite bad diarrhoea for a couple of days then for the following three to four weeks had to go several times a day passing small amounts but a lot of mucus.
The mucus seems to have stopped now but still suffering with the explosive ones.
I will be having the camera placed where the sun doesn't shine next week so hopefully nothing too bad shows up.
I could always eat plenty of peanuts and get a job as a pebbledasher
