When I get the hug, I have that same feeling about ripping the bra off. It relieves it a bit. However, mine is down a little lower that where you are describing; right around the band area of the bra and below.

With the tightness that you are feeling and the numbness and tingling, I would encourage you to call your neuro. It sounds like you may be in a flare.

I do hope that you start feeling better soon. Let us know what we can do to help you through this.
