I am suffering from pain in the lower middle part left side edge. I mean where the stomach starts after the chest .once I visited a doctor for treatment, he told that it's acidity problem. (with out making any test, he suggested some medicines but it was not cured. So the major problem is now I am getting blood from my mouth in the morning with my saliva. Last I fall off my bike and I got some blows. Some days after pain started in the middle edge lower left side .now I am getting blood in the saliva morning time. When the time blood comes from my mouth my throat burns the day. Please suggest me what might be the problem and suggest some medical test to diagnose the problem. Please give suggestions as soon as possible Thanking you.
