Well Allen, it seems that things have began to make sense now after your recent examination, your current problem was caused by having been on the respirator for so many days. Temporary damage to the vocal cords and to the nerves in the larynx are frequent complications. The good news is that your problem does not seem to be permanent and that with time and rehabilitation things will fall in place again. A friend of mine under the same circumstances could not swallow or speak for many weeks after he was removed from the respirator. You will have to arm yourself with a lot of patience because you're for a long haul.
