edema
"I have had edema before in primarily my left leg, however, it usually goes away on it own.  After some yard work in the heat, I was quite swollen in especially the left leg and as the leg went down, a heaviness settled in my chest and I could barely breath. I was taken to the ER after I started fearing a heart condition and was found to have heart failure with a normal functioning heart.  I was given furosemide by vein in ER and was admitted.  I was sent home after testing with a script for two 40mg twice a day and feel much better.  I still feel really tired after very little exertion and have had some cramps in my feet. Overall, I feel much, I hope that after losing some weight, I will be back to normal very soon. This is a wake up call."
