Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain feeling of lump in throat also known as Globus Pharyngeus when nothing abnormal can be seen can be due to causes like Stress,
Acid reflux,
Diverticulitis,
Eosinophilic Esophagitis etc..
Stress and acid reflux are the commonest culprit..
You need to consult an Otolaryngoloist or a Gastroenterologist and get evaluated and a thorough clinical evaluation and investigations like upper G.I Endoscopy, Barium swallow etc can be done to rule out the exact cause of the problem and treat you accordingly.
Cutting down on stress by doing yoga and breathing exercises can help..
In case of acid reflux antacids,
proton pump inhibitors like Omeprazole or
Rabeprazole and dietary modifications like taking small frequent meals, avoiding heavy and spicy meals, doing moderate workout, taking walk after meals, taking dinner atleast 2 hours before sleeping,drinking plenty of water, taking probiotics like Yoghurt in diet can help..
Other causes if diagnosed will be treated accordingly.
Hope this information helps..
Thanks and regards.
