Please take a look at my X-ray and ultrasound reports. I've had a cough for 25 days now, with episodes of coughing so hard that I vomit, which has happened about 90 times. The coughing only happens once or twice a day, but it can go on for around 35 minutes each time. I also have mild to moderate pain in my abdomen and chest. My weight has dropped from 78 to 65 over the past three months. Initially, I was told I had malaria, but the test was positive one day and negative the next, so I'm not sure about that. What do you think could be causing the cough and vomiting?
