Hi, I Didn't Know That Anybody Was Online Live. Recently

Hi, I didn't know that anybody was online live.
Recently I have been going to a Cardiologist. I saw him on Tuesday. I thought I was just going because of poor circulation problems, which I do have. I have been wearing compression stockings that have helped for each day but I still havine swelling. I have been taking lasix and he increased it to 40MG. I was upset on Tuesday with the diagnosis I saw as secondary (I think) of "conjestive heart failure" {I am just mentioning that as to my state of mind. )Last evening the upper part of my left arm was sore.. but today it hasn't really bothered me. Should I be concerned?
