I had a stroke in '19 I was left with dysesthesia all on the left side of my body. I have tightness on the whole left side. I can tolerate the arms and legs and sometimes my face and especially my hand but when it tightens up on my ribs around the breast area it makes me feel like I cannot breath. It feels like someone is sitting on my chest sometimes and it makes it hard to breath even though my oxegen level is fine. Putting an ice bag on it helps. Laying down helps me. It seem to appear when the weather changes to cold or a storm coming through or high stress. Doctors do not understand this problem because it is not a visible thing. I read it is what MS patients suffer the "MS hug"
