The pain in the mid portion of chest can be related to the gastritis or due to heart disease if there is any numbness to the limbs, sweating, light headedness.    Gastritis can be in the upper part of the abdomen with burning sensation and will be relieved on antacids.

I would advise you to go to the ER and get evaluated and undergo investigations such as X-Ray, ECG to rule out any rib fracture and heart involvement. You may require antacids. The following steps may help: - Don't skip meals,have a well balanced and healthy diet. - Reduce/ Avoid spicy,fried, fatty, junk and oily food - Avoid/ Limit drinking coffee, tea and carbonated drinks to once a day - Exercise regularly (minimum 30 min) - Increase daily intake of water to 3 liters - Avoid/Stop smoking and drinking if you have the habit - Reduce stress through methods such as yoga/meditation. If the problem persists or worsens kindly visit the ER at the earliest.

May be acidity or myalgia Try pantosac 40 mg empty stomach Avoid spicy food
