For the past 6 weeks I’ve been experiencing a few strange symptoms in relation to breathing, a lump in my throat that seems to happen shortly after eating and goes away with enough burping (haven’t had in 3 days since beginning 3mg melatonin nightly), and another issue of breathing difficulty. It’s not necessarily difficulty as it is an exaggerated awareness of my breathing and making sure I continue to breathe. I haven’t actually stopped breathing ever, but it also feels like the space in my rib cage won’t allow for full breaths. It’s very strange and doesn’t happen with any consistency. It hasn’t happened while working out at all. My o2 saturation can be 99% when it’s happening. Has anyone experienced this? It all started after I ceased all supplements (about 5 days after) which I did because of an overmethylation nightmare that I didn’t know what it was at the time. I have histamine intolerance but no asthma. I’ve had chest X-rays and doctors listen to my lungs and found nothing. I don’t get it.
