This is a symptoms description I typed up for my doctor in preparation for seeing him about abdominal pain:
Symptoms
Nausea, lasting 5-8 hours, usually with very frequent burping for the duration and dull gas-like pains. Episodes begin between 5 p.m. and 2 a.m., although there is occasional mild queasiness during the day.
Frequency: Every three to 10 days for seven weeks. Perhaps eight episodes total.
The first episode occurred after eating a large meal later than normal, with discomfort starting within 10 minutes of finishing. Only the first and second episodes were so directly connected to eating.
There is no sensation of heartburn, and no subsequent diarrhea or constipation. Flatulence is usually minor during or after episodes. I’ve noticed no fever.
There is little if any vomiting. The worst episodes had the free-flowing saliva that proceeds vomiting. Induced vomiting had no effect on the intensity or duration of pain.
Pain is fairly severe for the worst episodes. Pain is fairly constant (not relieved temporarily by the burping.)
Once an episode begins no significant relief is provided by antacids, pepto-bismal, acid reducers, simethicone, “Lactaid”, “Beano”, vomiting or antihistamines.
I’ve been unable to isolate any consistent food “triggers” (such as coffee, grease, sugar, acid, dairy, meat or high fiber). I suspect that eating many small meals of bland food would reduce the problem. Once or twice, I’ve had dull pain on a nearly empty stomach, but it was mild compared to other episodes.
I’m unsure about the prophylactic effectiveness of acid reducers, but have been taking generic Zantac occasionally.
I haven’t noticed any connection to body position, such as not lying down in the evenings.
My doctor figured it was acid reflux at first and had me take acid reducers which helped not at all.
Eventually I got an ultrasound which showed “sludge.” The gall bladder came out a couple weeks later and things are fine… except for thousands of dollars of uncovered medical expenses that show up from new, unexpected places month after month.
