I wanted to come back and thank all who gave me advice yesterday when I had an awful flare up. Today is a new day. I had this awful left sided pain before, and my doctor has told me that it is not related to my heart...thank God. It is called costochondritis.. it mimicks a heart attack, your stomach feels upset, and anxiety does kicks in. I took ultracet, and took a long nap, and I feel much better now. Thanks again. It sure helps to know that there is someone outthere who listens and understands you.
