Bit worried. Any ideas on these strange pains.

Last week I started to feel a pain in my left breast and arm pit. It came and went and I only noticed it every now and again. I had a good feel around and can't feel any lumps of bumps.
Over the last few days it has been there more and sometimes I feel it in my shoulder or running down my arm. It feels like it's water trickling down inside my arm and my hand goes cold and feels weak. At the moment it's in my upper left arm and top of shoulder and feels like a burning feeling. It is not very painful but annoying and enough to be a concern now. The breast/armpit area is not tender to touch and I can't seem to find a particular place where the pain radiates from.
I will definitely be going to see the gp if it carries on but just wondered if anyone had had anything similar or had any idea what it might be?

Ok it's been there all evening. Not really painful just uncomfortable and.....there. It's definitely in my upper arm and shoulder tonight. It feels like it's going down the nerves in my arm. Hard to explain.

Doesn't fit exactly, but my DM had tendonitis in her shoulder and it gave her some weird sensations in her arm and hand. It has mostly cleared up now with just rest.

Hopefully it will turn out to be something nice and simple. Or just go!

This sounds like a trapped nerve to me but I think you should go and get it checked out.
