hello and welcome to health care magic,
The onset of lump in the throat is usually nothing to be concerned about.
All you need to do is take the proper ENT consult and Medications which will make sure the symptoms go away in a week or so. A routine treatment would involve any combination of antibiotics, painkillers and anti histamine
Also take plenty of warm fluids during the time.
if the lump persists beyond a couple of weeks or so then it has to be properly investigated by either needle cytology, scan and by endoscopy
. Get these tests done and get back to me or any ENT for this.
