Hey there - welcome to the thread where everyone has SOB and nobody has a cure (said in the Whose Line is it Anyway voice). I'm sorry to hear about your problem but rest assured you're in good company. You'll find lots of good theories in this thread as to what may be causing your SOB. The issue is that there are thousands of issues that could be the potential cause. I've more or less given up on doctors even though I'm not sure that's the best advice. It's hard to know what specialist to even go to... is it a lung issue? A GERD/Reflux issue? Is it anxiety? All three of these issues would require a different expert. You'll see a lot of people in this thread have some sort of GERD... I'm currently taking Omeperazole but I'm not entirely sure it's making a difference. I'm tried changing my diet, losing weight, taking vitamins and supplements, working out, and just about everything in between. I have a new theory though that's been working for me. First, if you're having a really bad spell I find it helps to lay on my stomach with a pillow underneath my abdomen. I'm not able to take great full breaths but it's a lot more consistent. Your lungs are more so present in your back than in your chest so it frees up that area when you lay on your stomach. Secondly, I've been having a lot of success doing upper back stretches. The last week I've been stretching out real good multiple times per day in that area and my breathing has been noticeably better. I'll do a child's pose for a few minutes and a variety of other positions. I'm thinking of booking an appointment with a chiropractic because apparently spinal alignment issues can put pressure on the lungs and cause breathing difficulty. I'll leave a comment if I keep seeing progress but please keep us all updated because if we all are constantly investigating it's likely we'll eventually get some answers.
