Hi @lindalew ! I don’t crochet any longer, haven’t for years because of arthritis. But I have, and do, experience heart palpitations. I have Afib as well as lung issues and different smells or ordors that can trigger my palpitations and other symptoms you describe. Another thing I’m thinking about is if you look down when you are crocheting, sometimes when I’m looking down, reading, on cell phone, etc, I get a funny feeling that will go into the palpitations if I don’t look up when I start feeling that way. I’m not sure why on that, some thoughts are that if I’m not paying attention to how I’m sitting, I have more difficulty breathing. Also, sometimes it is my eyes, if my glasses are off I get a dizzy, nauseated feeling. Sometimes it could be a pinched nerve in my neck. I don’t know why these things are connected with me, and I’m not saying these things are what’s going on with you, just explaining my similar experiences and maybe something for you to go on in figuring out what is going on. Teresa has some very good questions about your overall health and if you experience these symptoms at other times too. If you haven’t, I would encourage you to talk with your doctor about these symptoms.
