|Not my x-ray but this is basically what a barium swallow does.|
After that was done there was another part. My stomach was essentially turned into a grade school science fair project. That's right; I had to eat bicarbonate of soda and vinegar. It was pretty cool though. He gave me a spoonful of the soda and told me to put it on my tongue. After that I had to down the liquid like a shot. It looked a lot cooler than it felt and tasted. That was not as fun as the crunchy milk.
In the end he said everything looked almost perfect in there. So it seems the problem is tonsilitis. Now I have to wait until the end of next month to meet the doctor again and go over the results properly and, hopefully, arrange to have my tonsils removed.
The worst part of the whole ordeal was actually having to wake up super early. Because you aren't allowed to eat anything up to six hours before a barium swallow they tend to be done early in the morning.
