Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. You have just described what is probably odynophagia. I would like to know whether the pain occurs only on swallowing or is it increased on swallowing and is present otherwise as well. In any condition, there seems to be a damage to the structural component of the neck which may include something as minor as muscle spasm to trauma to the bone or neck. You should ideally meet a neurologist to examine and confirm the diagnosis and thereafter go in for an MRI of the neck. Do let me me know the report as soon as possible. Meanwhile try paracetamol for pain (if it is continuous) and try liquid and soft diet- it may afford less pain when swallowing. Awaiting your report. Hope I have answered your query. Let me know if I can assist you further.
