strange chest noise -like a 'whirr'

Hi.
For about 3 months now, I have been having neck 'pain'.
It takes different forms and I would describe it more as irritation, like something is stuck or inflamed inside.
I saw an ENT specialist 2 and a half months ago - he diagnosed globus hystericus, stress, etc.
I have also had chest pain in this period, on and off, at the top of my stomach just below the ribcage, which hurts a little to the touch.
Over the last few days, I have heard a weird noise coming from the chest, like a 2-second noise which is hard to describe but nothing like the noises you get with a cold or phlegm.
So at the moment my neck is feeling irritated, like something is stuck both sides of the Adam’s Apple and I have a pain in my chest in the ribcage area - not too bad but constant - and I just heard that weird noise again.
Any ideas?
Regards Gary
