Dear Gemita, thank you so much for your message. I was feeling pretty low and having someone to talk to helps. I knew right away something was wrong. I kept getting a stabbing pain in my heart. I then developed very small lumps that kept growing and are painful. I get very itchy and then fluid started to build up where it got hard to swallow. I was in the hospital on strong doses of prednisone (I've had to take prednisone again since) it helps somewhat. Fluid is building up even on my back behind my left shoulder right down to my left foot and around my heart. In the beginning they kept trying to tweak my PM settings. It was a few months before they sent me for allergy tests. It also took a couple of months before they were done. They have been trying to find a solution for me. I'm very upset with Health Canada for not helping me. Time is running out for me now that the vein that the leads are in has collapsed. I have a wonderful cardiologist and he has a great caring team behind him. I am a very rare case and haven't been able to find out any information about my type of allergies on the internet. If I was rich I could go to the USA for surgery. When I got my PM my heart beat would drop as low as 25 and go up well over 200 and it stopped 960 times in 8 days. I'm very dependent on my PM. I again thank you for talking to me. I'm very grateful for this site.
