53 yr old female....240 lbs. had 2 umbilical hernia surgeries and dbl mastectomy all about 6-8 yrs ago. Had breast reconstruction 3 weeks ago. I have acid reflux to begin with, but, last week I started experiencing tightening, burning and cramping in the upper center area of my abdomen...between the esophagus & stomach. I then became nauseous and vomited some pretty acidic bile that gave me a sore throat for over 24 hours while in pain. The ER docs said ct scan didn’t pick anything up. I’m treading very carefully now because I still have cramping and it’s accompanied by nausea. I don’t mind throwing up because I know it can rid the body of toxins if need be, but I lost 10 lbs from last weeks marathon. The cramps are spreading up & across my chest as well. I also get a thick coat of acidic phlegm as this happens.
