Stomach sympotms: You may have gastritis (inflammation of the stomach lining) or stomach ulcer. Try to avoid foods known to cause/aggravate discomfort. Try zantac (ranitidine) or Pepcid twice daily before meals by 30 minutes or Prilosec over-the-counter once to twice daily also before meals. If other symptoms occur or your condition is not getting better, see doc.
