I've also had mine for two years. If it had been better explained to me how it works and the limitations -- I probably would not have gotten it inserted. I too have had pain in my chest where it is inserted. I was told this would last up to the first year allowing for the nerves to heal -- but it still bothers me from time to time and I also get that tearing feeling and it can be quite painful and uncomfortable. I don't lift weights but if I am doing lifting around the house or certain activities -- it seems to irritate the area. I'm sorry to hear that the events that you hoped to have recorded -- were not picked up. In March of this year, I had my parameters adjusted. Previously, it was not picking up anything unless my heart rate was below 45 or over 145 (I think) -- anyway, I got the upper limit put down to 120. I was under the impression when I got this thing that I would essentially have a 3-year, 24/7 heart monitor that would pick up all of my arrhythmias. Not true. I was told at my 2nd year appointment that it doesn't pick up on PVCs, PACs, and the like. It can detect atrial fibrillation. Darn -- if I had understood this, I would have foregone the procedure -- as it was quite expensive. Just a couple of weeks ago, I was having racing of my heart at night. I did contact my cardio office and it was all caught -- but had the parameters not been adjusted, it would not have been.
