My Partner Brian Was In The Kitchen 7 Days Again

My partner Brian was in the kitchen 7 days again when he got a sharp pain on his right foot his foot is swollen. He borrowed crutches from a mate and has been getting by on them but his foot has not gone down and is still really swollen. Two days ago he came up in a rash on his right leg and foot. To start with the rash was red but now it's gone purple and rather than looking like spots they have now gone really blotchy. I have tried the glass test and it is not fading even slightly. He has got them coming all over his body but not as much as his leg.
