i have an aberrant right subclavian artery which compresses my trachea by 40%. This difficulty breathing which comes from this has slowly worsened over the years. What I don't understand is why, at rest, sometimes i get very bad days where i can't get any air in. I've done more research than I can remember, but no one has any ideas. Surgery is too dangerous and we still aren't to sure why i have such symptoms. Other symptoms include difficulty swallowing, losing feeling in my legs and arms during exercise, chest pain, palpitations and so on. I'm not sure what to do, but I'm hoping someone has some idea of what to do next or they might know of someone who has similar problems!
