Throat MRI?

I’m freaking out. 

I’m 25 and have been suffering with a sore throat for four weeks on the right side around the tonsil area. 

I saw an ENT last night that put a camera up my nose and down my the throat and had a good look and poke around. He thinks it could be a tonsil stone that he can’t get at. He also said that it wasn’t anything to worry about. 

Then I saw another ENT tonight who didn’t use a camera and said I need to go for an MRI. He also says that a tonsil stone doesn’t cause pain. This ENT was private so the scan would cost £££. 

I’m confused as seeing the ENT last night totally put my mind at risk. But seeing one tonight has really worried me. 

I’d appreciate any advice...
