I had to be hospitalized 2 years ago for chest pressure. They thought it was heart related. I had tightness in my upper chest area. Nothing came up, I even had an angiogram, clear. Now, I know it was most likely the MS hug. As long as you're not running fever or having pain or nausea with it, it's probably the MS hug. (are you sure you don't have pneumonia or anything like that?)
When I get it, it usually lasts a couple of days and then it goes away. I haven't found anything that helps. Maybe someone else on here will have some helpful tips. Be sure to keep track of your symptoms in a daily log. :)
Don't be so busy doing good
that you neglect to do what's right!
