Hi Odin, you seem to be here and on a roll, so you may see this. DMSO is not a legal medicine, but it is used on horses, so you may get some via a vet, or a horse owner. I picked up a litre bottle given to a charity shop by a horse owner Good luck with your diseases, sound awful.
And pleased to hear you "got" some land. We are on the land. My father was born in WA... Wagin.. in the wheat belt.
