Chronic Hiccups, sign of impeding renal failure. In the past, I would get extreme hiccups day out and day of show.. so bad I would burn my throat from reflux, I was popping ant acids every 30 mins in addition to prilosec. Sucked, I remember not being able to eat for a few days after the show. Hiccups would go away rather fast though, post show.
I work in the hospital, I asked one of our physicians why that happened. He told me to speak to one of our nephrologists.
I did, 2 of our nephro's said it was prolly due to acute kidney stress from blood pressure instability, electrolyte imbalances, just from high gear usage, diuretics, water depletion, all that. More on the acute side though, due to the fact my renal values have always been, cross my fingers.. good.
Keep in mind though, hiccups could also be.. NOTHING of concern.
