I just found out the other day what a MS Hug was all about. I have been having these same horrific pains under my right breast going around to my back. My Dr. couldn't find anything out of place. I even went to my Chiropractor to see he could help me but no. I had googled the MS site on my computer the other day and came across the M.S. Hug. I soon learned that I was having the same sharp pains that so many of you have experienced also. I'm so glad that I am not crazy and in fact that so many of you have described the exact experience that I have been dealing with. It sucks!!!!
