I've been in the hospital for the last 5 days with congestive heart failure. I had been swelling all over for a few weeks and didn't know what from. I had just started Neurotin about 6 weeks ago and thought it might be from it. So, I stopped it but the swelling continued. I got to feeling so poorly that I went to the ER to get it checked out. Besides, my doctor daughter kept calling me and bugging me to, telling me that I could be in either kidney failure or congestive heart failure. Turns out she was right! I guess of the money we spent on those last 8 years of college paid off !!!! lol So .... if any of you start swelling up -- my hands, ankles, and feet were swollen ..... make sure you get it checked out. There is blood work to diagnose CHF as well as a chest x-ray. Come to find out, it may be caused by severe sleep apena. Sleep apena not treated properly will cause the right side of your heart to not pump properly and cause you to retain fluid which will fill up your lungs, too. They pumped 12 lbs. of fluid out of me! Now, when I get my strength back,I have to get caught up in reading posts!!
