Choked on a chip, scrtched my esophagis, now throat and chest is sore, should I worry and how to releave pain?

Soft, nonacidic food. If you have no fever, and you have no palpitations, you are probably fine. Keep the stomach acid off of the scratch by taking either an over the counter histamine blocker like Zantac (ranitidine) or tagamet, or a proton pump inhibitor such as omeprazole. Avoid acid foods and beverages.
Will resolve in. Dr s is correct this should resolve in a day or 2 at the most.
