Hurting your ankle does not have anything to do with your swallowing, unless you are taking pain medications (Example: NSAIDs such as motrin / ibuprofen, etc). These NSAIDs can cause what is called pill esophagitis and therefore cause difficulty swallowing. Another problem is alcohol consumption: that puts you at high risk for falls and trauma (hurting your ankle), and it will also cause gastroesophageal reflux disease, which can also cause esophagitis, and end up with trouble swallowing and burning sensation in your chest and mouth. I advice you to cut down or quit alcohol, and avoid NSAIDs if you are taking them.
