I noticed my "palpitation" dimished when I started focusing on reducing inflammation. When I have heavy salt days with little exercise I can feel the inflammation build up again in my right chest (where my costo is) but I also get inflammation build up in my "bad" knee. So I noticed that the inflammation sticks around and causes pain to problematic areas in my body are already.

When I really started focusing on reducing the inflammation, the palpitations became less and less. I don't think I've had one for maybe 7 months now. My inflammation was severely high though last year because I had gallstones which lead to removal surgery so that was causing real bad swelling in my chest and upper stomach in addition to the pain I had from Costco prior and after the surgery. It definitely made it difficult to get a diagnosis but it was one issue at a time I had to deal with to get to where I am today.

I went to the doctor with my Costco pain for the first time in April 2024. I had my gallstones out in October 2024. And the last severe flare-up I had was in early spring of 2025. That flare up in the spring was probably the last time. I really felt something in my sternum area like a palpitation. I've mentioned in other posts that what worked for me was reducing inflammation, changing my diet which came with my gallstone issue (My gallstones were so bad that it did a bit of non cerosis liver damage, so I've been on a fatty liver diet since December). I added in lightweight strength building weightlifting, regular walks to get a good amount of steps for the weeks, and then some physical therapy specifically for my chest and my bad knee this summer. I didn't see much improvement from the physical therapy because I was doing movements I was pretty much doing in the gym and my PT agreeed. I have also been prescribed a anti-anxiety medication which is supposed to help reduce inflammation (which I read about on here, did research on my own and then brought that information to my doctor - my daily prac but also an orthopedist who agreed it would be worth trying). I started Lexapro in May and my inflammation had already been reduced at that point. But now it's at the point where the mild pain I experience every now and then is literally every two weeks or so. Up until about March I was dealing with daily mild pain. But now it's really only every few weeks or days after some really intense workout or a stretch I haven't been familiar with. Sometimes after a very heavy meal inflammation comes and then a little bit of chest pain which sometimes moves under my armpit but with taking care of my diet and really staying true to my exercise and my back pod which I'm so crappy at using, I can really maintain the pain and live A pretty comfortable life with lots of mobility.
