Hi.
You are experiencing difficulty in swallowing with a feeling of a lump in your throat. There could be a problem somewhere in your orophayngeal area, or in your esophagus. There are a number of conditions that can bring about these symptoms. An x-ray may not be sufficient to diagnose a problem.
It would be best to consult your doctor for further evaluation.
Good luck.
I had the same sensation and still do at times. I'm a smoker and my mother died of throat cancer so needless to say I was concerned. I had an ENT take a look (stuck this scope thru my nose into my throat and found nothing abnormal. Stress can cause that sensation - there's a name for it, though I can't remember what it is. Anyway, if it concerns you, make an appt. with an ENT.
