You have given enough Rhus Tox!! What colour are the eruptions. Is there is bluish tinge to them? Is the itching worse or better from the warm bath. Quite honestly the didease is just running its course. The itching is the worst thing and I think we've stopped that with the Rhus. Tox. If you still think he needs Puls. get some 30. I think you can get it at Boots. If not try a health food shop. Where about do you live?
