Bacterial Infection
"I took two pills. the second pill seemed to have been stuck in my chest about three hours after I took it. I had heart burn like I had never ever had before. Then started nausea and vomiting for about 24 hours. Went to ER they said my esophagus was swollen and inflammed and gave me meds 
Two days later went to digestive doctor he said that pill is common for this.  It has caused people to go through same thing. It has been almost a week, with two visits to ER and now a appointment set up to see esophagus specialist. I am finally getting  better. Hopefully this night mare will be over soon. Just be cautious, this has been a bad experience for me."
