Back in April I posted that a cousin of mine in NZ had either DMS or DSM.

It was suggested it could be something to do with Multiple Sclerosis but it turns out it isn't this.
I know for sure now that it's DMS and something to do with the marrowbone.
His immune system is very low and he said he has only months to live.
I have googled this and can't find anything called DMS that is to do with the marrowbone.
Does it ring any bells with you? x
