Weird feeling - does anyone else get this?

[TinyGoldfish]

Bit of an odd one:
Basically my right side feels really uncomfortable. The right of side of my neck, the right side of my right breast and that right rib area, my right arm and hand.

It doesnt hurt exactly but is really uncomfortable and is starting to drive me mad.

When it's bad I can't even let my hair touch that side of my neck, I can't hold a pen for a long time and I have to keep hoiking my boob up! I'm struggling writing this as I'm on my phone and my right thumb isn't cooperating. It feels like my muscles or skin is really really sensitive.

If I had to describe it I'd say it was like a white hot pain but with discomfort instead of pain (if that makes sense....).

I know it doesn't sound like very much but it really is driving me crazy!! Any ideas?
