Dear friend there is no specific technique to self remove the stuck foreign body. only thing that you can do is stop eating and try to cough
out as forcefully as you can ,. dont try to take out or vomit. you may do traumatise the soft oral mucosa
. Presently you should consult the E.N.T Physician. there is very unlikely that you have impacted foreign body in throat. there may be some irritation in throat that may mimic like foreign body.
