It started Thursday evening, huge belching, had a hard time sleeping, went to work. Huge belching and upset stomach, by Friday nite about 8 I was very uncomfortable with very sore around my left side. Went to emergency room at the hospital. Gave me morphine and gravel. Next morning they took a C T scan and everything was normal. Now tonight I feel very sick and just vomited. Any answers as to what s going on??
