Welcome to HealthcareMagic Forum.
There are few things which were noted in your history
1. Frequent clearing of the throat
2. Urge to cough
4. You have got almost all the important tests done, to rule out cancer and they are negative
Well, one thing has been ruled out, that you do not have cancer. Secondly, it can be any one of the following conditions Laryngo-pharyngeal reflux or globus hystericus
. You are already on prisolec, so please continue that. Apart from all these things, drink plenty of warm water, avoid stress
, keep yourself relaxed, avoid coffee/tea/fizzy drinks/alcohol/smoking
if any. With these, probably your symptoms might reduce. Keep informed.
