Erosive Esophagitis
"I went to the ER yesterday thinking I was having a heart attack.  It seems (will be further explored) that my low level GERD for which I&#039;d been taking 20mg omeprazole, eroded my esophagus and I had esophageal spasms - unbelievable painful.  Took the generic Protonix this morning and what a difference.  No side effects whatsoever, but it&#039;s early days.  Will see my primary and GI doc soon to delve deeper.  However, I couldn&#039;t believe the instant relief."
