I am a 25 year old female. I am suffering from severe pain on the left side of my ribs, near the upper abdominical region. The pain worsens while breathing in. The first breath hurts the most. Lying on my left side is painful, and stats hurting my shoulders and back slightly. I experience pain both breathing in and out. In march (earlier this year) I developed a sevre cough which last me for about 4-5 weeks and then disappeared. After that I even had a bout of severe gastritis and bloating. Finally, I went to an area at a high elevation (which was extremely cold as well) and towards the end developed severe back pain which affected my breathing. Now the only pain remaining is in the upper abdominal region under the ribs, on the left side. Please help.
