I have a burning feeling in my ribs and under my left breast and sometime in my chest. Could it be acid reflux? It started last night at 8pm and it went away, but now it's back this morning. Should I go to the hosptial or will it go away?
Yes, this could be acid reflux. It can also be related to your heart or an infection or other things. If it worsens, is severe or if you are having other symptoms such as difficulty breathing then you should get it checked. If it keeps coming back then that would be another reason to go to the doctor.
