I was eating tortilla chips and swallowed a sharp piece which has caused pain in my throat. what should i do to relieve the pain?

Chip chip: Such abrasions in your pharynx normally heal by themselves. They can be caused by a variety of foods that are hard. For temporary comfort you can use ice chips. If there is swelling then salt water gargle may be very helpful in reducing the swelling. It should improve in about 4 days. If not then please see your primary care doctor for better evaluation.
