You could try bathing it in a saline (salt) solution. It might help him out.

If the Dr has given you Canesten he obviously suspects a fungal infection. Did he take a swab to confirm? Try boosting his natural immunity with giving him yoghurt containing lactobacillus acidophilus, avoid sugary foods as this "starves" the yeast fungus and also avoid yeasty foods like vegemite. You could also try bathing with a very dilute solution of warm water and cider vinegar.

both replys are great advise, i would go back to the Dr if not looking like it is improving in 24/48 hrs, once the right treatment is started then it should improve quickly, lots of nappy free time too.

I assume the Dr checked to see if the foreskin was ok? As in not too tight and as krisp says assumes a fungal infection.
All the advice above is great.

make sure you increase his fluid levels too. it'll reduce the acidity of his wee.
