OK, so you really want the solutions?
Here they come... not for the faint-hearted.
A bolus is just the name for the normal "balls of food" when we eat and swallow, not usually getting stuck.
If people eat bits of cows, the meat fibres can stick together more than other food and even get stuck. That's the reason for the nickname "steakhouse". Doesn't have to be meat, it can be not chewing, alcohol, GERD.... And fizz can help a little bit by bringing gas into the goo.
In my case I have this Schatzki ring above the stomach, making my oesophagus narrow. I don't eat animals. And any food will do, sometimes even yogurt etc, and even drinking a lot with my supps is no guarantee. If I don't wait long enough between mouthfuls, pressure builds up and it all sticks together and won't go down. Before the gastritis, rubbing and tapping tummy/chest (above and below sternum) did help get it moving again, sometimes fizz helped, if it wasn't too bad, or had moved a bit. If not, it makes it worse. When I try rubbing at all now, I need to be near the bathroom, and essentially I've given it up, the chance of it helping is about 5%. Either it goes down or has to come up, there's no middle field any more. The "up" is sometimes easy, but it's got increasingly difficult and strenuous too, even tho the method isn't complicated. Means I have to be extremely mindful with every single mouthful and immediately stop chewing and remove everything incl. liquid out of my mouth if I feel the slightest build-up of pressure.
What makes this interesting is it's another example for believing something may be fibromyalgia. Someone else in my fibro clinic had it too. And I thought it made sense, thought it was the oesophagus-muscles cramping. But then I was wondering if it is a symptom of eosinophilic (o)esophagitis (EoE) or MCAS (the oesophagus mast cells playing up) and just wanted to get it checked, like everything. It wasn't visible last time the gastroenterologist had a look 2 years ago and wasn't visible to two ENTs in the meantime either. When he compared the pics he could now see a hint of it 2 years ago and it has now become "impressive" as he put it in his report. Only reason I don't think it'll get worse is because I've got my food triggers sorted out perfectly, so GERD is no longer an issue.
