I have developed a really painful condition that feels like a heart attack when it happens. I've been to casualty twice in the last 9 months with this, and it's happened 7 times. In between I've been diagnosed with Type 1 diabetes (5 months on insulin). I also have coeliac, thyroid disease, asthma and lichen sclerosis. I'm now 62 and seem to develop a new autoimmune condition every time I sneeze. Anyone else with multiple problems? Anyone else have this painful condition? Each time it happens I'm convinced I'm dying, and I'm really scared it will happen again.
