My mother s (68yrs old) throat started to swell up, became very sore, and she can t speak louder than a whisper. Seems to be more acute on right side which made me think possible stroke but she doesn t have any of the other stroke symptoms (face droop, confusion, slurred speech etc...). She survived lymphoma years ago. I m really concerned because of the speed it happened. It started out of nowhere and and within 20mins she became very sore and lost voice. For the moment it doesn t seem to be getting worse but not getting better. We were gonna wait to see if it s just a temporary reaction to something and will go away on its own, but should we be more concerned and go to emergency?
