I have Tourette Syndrome (I am 43) and I am aware that this disorder is genetically transmissible. However, I have a 4-year old daughter (no Tourette symptoms yet) who began a non-stop throat clearing ritual a week ago. She would clear her throat every 5 to 30 seconds, all day long, since the moment she gets up, until she goes to bed.
Now I'm not assuming this is Tourette's, she would need to be diagnosed and hasn't displayed any other symptoms. There could be many other reasons. My father spent his life clearing his throat and so has my sister (and both attributed this throat clearing to their asthma). I do have this frequent throat clearing thing, but I do not have asthma; and I never felt this was due to Tourette's (I know what a tic feels like, and this frequent throat clearing doesn't feel like a tic). It could be a throat secretion problem shared with some members of my family.
What other reasons can my daughter have for clearing her throat so frequently like this? She says she feels "bubbles" in her throat. She probably means some type of secretions.
I would appreciate having some input before I take her to the doctor (I want to be better prepared).
