Bruising of cervical esophagus. Course!

Three four days back I was chewing supari which I swallowed. I thought it would get stuck in food or wind pipe so I very forcefully tried to vomit by inserting a finger in the mouth. However, there was no vomit, only some spit and little brown kind of thing(not sure if it was blood or supari) . After this I felt as something is still stuck in my cervical esophagus. I consulted an ENT who said nothing is stuck. However, I still keep in feeling a little uneasy/pain in the cervical esophagus. The kind of pain you have when you get hurt. Little burning kind of sensation. I feel it more prominently today than I felt a few days ago. I also feel a little bit of swelling around the neck area. The ENT had prescribed zincovit which I have started taking only from today. After reading the net I fear that I might have had a tear/ rupture of the esophagus. However there have not been any more vomiting or other problems apart from the little pain on the cervical esophagus area. Pls suggest a course
