@chris77- I recommend seeing/talking to someone who looks at the entire body system. Doctor of Osteopathic Medicine/Functional Medicine Doctor/Body Systems worker. It sounds like the heavy sneeze caused quite a bit of force and shock to your nervous system. I would also include that in trying to get calm. Don’t underestimate the power of the mind/nervous system. It can bring so much attention to an already stressed area, preventing relaxation and homeostasis from happening. With lack of feeling at ease, your senses are on high alert. If you can find someone who can calm your system and work on getting your sleep restored that will help immensely. At this point you can not leave that part out. The “parts” department, i.e. ENT, Gastro etc...will not discuss nor help you with this part. The positive is that it was a sneeze that caused you to feel the discomfort. So it was a natural/normal occurrence. Did anyone ask you what your stress levels were like prior to this or at the time? If already in a tense state this can contribute to the way the body responds. Look at both entities. I hope this helps.
