I was drinking soda and suddenly i couldnt swallow it and it wouldnt go down or up it was just in my throat. i didnt cough or anything but after trying hard to swallow, it went down. how do i know if it went down the right pipe?

If not coughing: If not coughing and not having trouble breathing, then a person can assume she swallowed the soda down the correct pipe. If the soda went down the wrong pipe, a normal person would be coughing uncontrollably until the soda comes back out of the wrong pipe, or until the soda got neutralized or otherwise diluted so that it is no longer irritating to the lungs (that's where wrong-way soda goes).

Esophageal spasm: A cold drink can induce spasm of the esophageal muscles and cause the symptoms you experienced. There is no lasting harm. Have a healthy diet, exercise 30 minutes/day, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/.
