welcome to Healthcare Magic.
I can understand your apprehension related to current symptoms. From your history it appear that you have some form of anxiety
disorder This symptom also known as globus hystericus
. Combined treatment in form of medicines (like SSRIs) and cognitive behavior therapy is best for such problem.
History of Bulimia also increases chances of developing anxiety disorder. Apart from that tingling numbness
in throat can occur in following conditions too which need to rule out after investigation and examination:
-Growth in throat
-Increase tonsil size
Wish you all the best.
