I am 19 years old female and in good health. Lately I have been experiencing pain in my upper back and the middle of my chest above my sternum. This is happening right now I am trying to figure out if I need to go to the er or what I can do to make this pain stop.
Thanks for your question on Chat Doctor. I can understand your situation and problem. Pain in the middle of chest (substernal) and in the upper back is mostly due to musculoskeletal cause. So better to avoid heavyweight lifting and strenuous exercise. Avoid movements causing pain. Avoid bad postures in sleep. Start painkiller and muscle relaxant Chat Doctor.  Apply warm water pad on affected areas. You will mostly improve in 1-2 weeks. Another possibility is HERD (gastroesophageal reflux disease). It is due to laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the esophagus and cause central chest pain. So avoid stress and tension, hot and spicy food. Take proton pump inhibitors. Don't worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks.
