Hi happykuffy,
I don't have any direct experience with MRSA but I have heard that it is especially tough on dialysis patients and people who are immuno-suppressed.
If anyone is interested in reading more go to:

I can imagine that many people might try to self-treat something like this, and there's a danger of waiting until it's too late for treatment.
It sounds like you dad is getting good treatment and I pray he is feeling better soon.
All the best,
Karol
