I have multiple sclerosis and i wake up choking and grasping for air. i have choking episodes all day (at work, while driving,etc).i am afraid to eat.

You need to consult: a GASTOENTEROLOGIST who does esophageal MOTILITY studies...Sound like a REFLUX issue! Hope this helps! Dr Z

Several points: You may have a sleep disorder, such as sleep apnea, but a better explanation might be sinusitis or GERD. Would urge you to visit internist and undergo full examination. Would also get your neurologist into the loop, as regardless of cause of the above, you need a potent disease modifying agent for your MS. It is very unusual for MS to affect breathing or cause intermittent choking.
