I know this has been talked about a million times, so I searched....but nothing came up.

I am having chest discomfort that comes and goes for the last week. It is under my left breast. Maybe like a tightness. I feel like I need to take a deep breath.

This actually started while I was taking my forth dose of Gilenya.

Yes it freaks me out being my left chest....but then it goes away, and I don't think about it again.

Years ago, I had what I think may have been the 'hug', but it was back tightness/discomfort/pain in the area of my bra strap....So, this is new to me.
