Not asking for myself (I use the forum for my own TMS issues of mainly back pain). I'm asking for my mother, who is in her early 70s. I've tried to approach the idea of TMS with her in the past, but she is very reluctant to believe. Her past issues (which I think are all TMS) are back pain, neck pain, frozen shoulder, allergies, hives, food sensitivities, etc. She has also had colon cancer. Her current issue is atrial fibrillation. She was diagnosed with mitral valve prolapse many years ago. The A-fib keeps coming on and she is starting to think that it is connected with digestion (from having part of her intestine removed during surgery for colon cancer 10 years ago). It can come on after she eats, and now she's getting fearful of what she eats. What is a good source for understanding truly medical causes of A-fib? (Or is it always TMS?) The doctors keep sending her home with a heart monitor, which I think might be their way of saying that they can't find a cause and wanting to appease her somehow.
