I had the MS Hug once for about 3 weeks. I could not breathe. My chest felt so heavy and my back was killing me when I would try to breathe. I explained to my PCP that it felt like a truck was sitting on my chest. Hurt like h---. PCP sent me to a Cardiologist. Of course they could not find anything. Also had a chest Xray done. Found nothing, nada, zilch. That is when I knew it was the MS Hug. Far from the hug I am used to

Take care.
