I’ve experienced several episodes of serotonin toxicity/syndrome over the past few months and believe that my body still takes a lot of time to get rid of serotonin. Every time I have an episode it always involves the heart and when the other symptoms are gone, mild heart pain persists. I read of this condition called carcinoid heart disease, basically it’s a heart disease caused to too much serotonin (secreted by tumor). But since the culprit is mainly serotonin, can people with chronically high levels of serotonin be at risk for some type of heart problem? I’m already experiencing persistent mild heart pain and I’ve only had this serotonin problem for about 3 months. Kind of scared
