Here's a link to an article on WebMD describing the problem and possible treatments - does sound like it's recognized as accompanying neurological disorders, which means US. Lists a variety of treatments, including exercises to train the muscles - sadly these are not explained. But DO mention it to your Dr! I confess, I saw mine this week, and forgot to mention it

Think I will give the nurse a call Monday as the last choking incident occurred while drinking a Pepsi behind the wheel - alone - very scary, but I did get my breath back fairly quickly that time. Hurt like hello, though. The anti-inflammatory is not doing much for me either - chest is still tight and hard to get a good breath. Ribs are v. sore to touch on left, has always been the right side before when costochondritis flares up.
