Hello Dear and welcome.
Thank you for your query.
Chest pain could be categorized into various conditions.
If you are experiencing chest pain on the left side of your chest, it would be best to get and EKG and an
echocardiography done, which could help rule out any heart conditions.
There is a condition called
costochondritis a.k.a Tietze's syndrome (inflammation at the junction of the rib and
cartilage) and can cause chest pain and discomfort.
I would like you to discuss your presentation in detail with your doctor and visit him/her to help ascertain the diagnosis.
If you have started exercise recently or have been doing some form of exercise involving your chest, chest pain is common, especially in the center of your chest, which is where the
xiphoid process (breast bone to which the ribs attach) is present.
Also, to rule out any gastro-intestinal problems, which present with
epigastric pain (upper abdomen, close to the xiphoid process), try to recall if you have been suffering from any gastrointestinal symptoms.
The best option would be to discuss your condition, intensity of pain, type, duration, aggravating factors, relieving factors with your doctor in person to help solve this problem.
A smart person would never delay a visit to the doctor, no matter how mild the symptoms.
I wish you the best of health and a long beautiful life.
