I am 20, male. Why do I have mild, constant chest pain?

The probable causes are the chest pain can be related to diseases involving the stomach, heart, lungs and the chest wall. The diagnosis depends on the type of chest pain pricking or vague and changes while breathing has to be noted. Shortness of breath has to be rated for the amount of work causing the shortness of breath. A headache may arise due to sinusitis or stress (tension). Heaviness in the throat may be caused by infection, regurgitation, etc. Considering the symptoms put together, I presume that it could be regurgitation. Regurgitation is partially or undigested food felt in the throat from food pipe after swallowing. It may be due to any one of the following: 1. A lax sphincter in the lower end of the esophagus. 2. Tight non-relaxing sphincter not letting food pass through (achalasia). 3. Increased abdominal pressure. 4. Esophageal diverticula. 5. Helicobacter pylori infection. The recurrent regurgitation will disturb the flora in the throats leading to repeated infection, sore throats and hoarseness. If severe may result in upper respiratory tract infections, sinusitis, and headache. Chest pain is described mild and constant seem to be heartburn due to regurgitation. There could be other possibilities which require detailed history and basic examination.

Investigations are not needed but it is important to follow preventive measures and if symptoms persist, get an upper GI endoscopy to determine the cause and to arrive at a diagnosis.

The preventive measures include 1. Do not lie down flat after taking food. Lie down 2 hours after taking food. 2. Make sure to eat half stomach. Split up the meals (six half stomach food is better than three full stomach food). 3. Cut down on spicy food and eat healthy and freshly prepared food. Have a balanced diet and take fruits and vegetables. Maintain a body mass index between 18.5 and 24.9. Try these measures. If symptoms persist, then you may consult a doctor in person to get the necessary medications to reduce the acidity, reflux, and treatment for a throat infection. The history is very minimal to arrive at a diagnosis and start a treatment plan. I advise you to follow the preventive measures and consult a doctor when symptoms prevail or worsen.
