Is this chest pain to do with GERD?

I'm 18 and have had GERD on and off for a few months, it's not been bad for a few weeks, just the annoying hiccups really, but today after eating some crisps (i think) i started getting this burning feeling in my lower left chest area just above my breast bone (upper breast).
I've had it before so i assume it is to do with GERD?
Is is Heartburn?
It's not servere it's mild, just really annoying.
Thanks .x.

You are probably right that this is just refluxing gastric acid. Make certain you stick to the right foods and avoid those that trigger or worsen episodes of reflux. I'm sure you know the routine but it bears repeating: Eat smaller, more frequent meals (4-6), chew food well, keep your weight down, avoid prolonged pressure on your stomach (includes tight clothing/belts or certain body positions), stay upright for 30-60 minutes after meals, don't eat within an hour of bedtime and keep your head elevated in bed. Use two pillows or place wooden blocks under the head of the bed to raise it to a 30 degree angle.

If you feel your medication at its current dosage is inadequate,or, if this continues or worsens report this to your doctor. Ask your doctor if you may take an over-the-counter antacid for breakthroughs like this.

If the pain is the same as you have been having, then yes, it's probably reflux related. Because you say it is a burning sensation, it makes me lean toward reflux and not anything cardiac. Does your reflux medicine help with the pain? If the pain gets worse, you have any other symptoms, or you need reassurance, talk to your doctor and have a simple EKG done.

Burning pain after eating does indeed sound like the GERD - try taking your antacids and see if that helps, and don't lay down after eating - stay upright.
