Does anyone know what MCS is or what it means please?

[fabwoman]

I have had a text from a friend saying she has got this and I haven't heard from her since and I am worried.

Could this be it?

Multiple sclerosis?

It sounds like the sort of thing she could have - Jess's suggestion - as she has other illnesses. No reply yet.

Oh dear hope she is ok, let us know what it is, when you find out, if you can.

I hope she texts.

I have heard from her today.

It stood for miserable cow syndrome.

I was so worried as well as she isn't very well generally.
