Thank you for the quick reply.
The symptoms your 9 year old daughter is having of feeling of soft "lump" in her throat or feeling of something stuck in her throat when she eats since for last few weeks is called as globus sensation.That is persistent or intermittent sensation of feeling of lump or foreign body or something else stuck in throat.
Its most common causes are:gastroesophageal reflux disease(GERD),abnormalities of the upper esophageal sphincter,stress,psychological or psychiatric disorders.
She may need upper endoscopy.Barium swallow test may be required.
The most probable & most common cause is gastric reflux(GERD).The burning sensation sensation in her sternum firther supports GERD as underlying cause.
There is nothing serious or dangerous .The exact diagnosis can only be made after physical examination & tests.So I advice you to make an appointment with her doctor & then accordingly she will be prescribed with medications to treat gastric reflux(GERD).
Hope this helped.
