Sorry to hear about your condition. Just recently I began having tight lump in throat feeling and makes me feel nauseous especially when I lay down.
A week before this happened, I was rushed to hospital as I fainted with apparent dehydration. All bloods fine and he put it down to stress.
The doc prescribed pills which would open up the airways and sinuses as he said the body can shut these down during such episodes.
It got me thinking because I NEVER had motion sickness or vertigo until about a year ago.
I haven't had a chance to go back to the doc but I really believe that blockages of sinuses can be contributing factors here, as I feel less nauseous when I inhale a nasal stick for example. I don't think it has much to do with foods I eat. But rather not enough oxygen and blocked sinuses. Just a thought.
Not really sure how to navigate this site, so I am posting a reply. I too have been suffering from the lump in the throat, constant nausea, stomach pain, dizziness, etc. These symptoms increased their severity in only a few weeks to constant. I was bedridden and could only find some relief by laying perfectly still with my head elevated. After a trip to the emergency room where I was subjected to a battery of tests with absolutely no result did I start my internet research which lead me to this site along with numerous others. I thought I had throat cancer and after a biopsy was taken at the ER trip and waiting for a week after for the results, did I find out that the biopsy was negative. My history is this - I have been taking a PPI for about 15 years, so I am used to dealing with "GERD". I sometimes supplement my PPI (omeprezole) with Pepic AC chewables (if I eat late or eat spicy foods). First, anyone that is taking a PPI should be taking B-12 supplements as the PPI inhibits the absorption of B-12. B-12 deficiency can cause severe nausea. This I have known and take 1000 mg per day of B-12. One of the constants that I have seen on this site and numerous others is that sufferers have had some sort of sickness requiring antibiotics before these symptoms started happening. This is the same in my case. This lead me to do research on the affects of antibiotics, which lead me to taking probiotics. I starting taking Nature's Way chewable gummie bears 6 days ago - two per day. And, remarkably my symptoms have decreased every day!! I woke up this morning and am almost symptom free!! Now, I also have stopped taking the Pepic AC, which I was eating like candy because I read that too little stomach acid is actually worse than too much stomach acid. So, I don't know if this will work for anyone out there, but after going thru this "non-named" affliction for months, I was willing to try anything!!! And....... so far, so good!!
