A few months ago I caught a bug and vomited several times over the course of a night. The following day i experienced pain at the bottom of my sternum that grew more and more severe. I lay awake with it all night, eventually taking some ibuprofin when it was chronic pain. The pain went away after the ibuprofin.

However, since then, a few times a week I have experienced the same pain, often after eating and sometimes I wake up with it. I have also felt excessively tired and generally ill though I'm unsure if this is related. Have I got acid reflux? What can I do about it? Often the pain is extremely severe.

Thanks.
