MS hug

Hello all,

pardon my ignorance, but I have a question about the MS hug.

This morning I woke up, not for the first time, with a weird and quite nasty feeling of severe pressure in the rear of my ribcage, the worst of it only lasted a couple of hours, but I can still feel it, I’ve had this before but thought it might be a chest infection, but I don’t think that it is now. I read somewhere that the MS hug is sometimes described as pressure, and now wonder about it?
