I had my first MRI today

Good evening everyone. I was sent on the 2ww pathway for some general swelling in my jaw and neck on one side - not huge but you know, you become self conscious when it is there all the time. It’s been a few months ( October 22) and it’s slowly got worse. After my 2ww appointment I waited only three weeks for my mri - which I feel lucky to have been seen so quickly. But I can’t help but feel anxious though I know that being in my 20s it is a likely to be something else. The radiographer and assistant were so lovely during my scan but what made me feel a bit weird and anxious after leaving was the radiographer saying if I don’t hear anything in two weeks to chase and asking if I already had an appointment with the ENT consultant ( which I don’t ). From the letter previously sent to my dr he thought it may be a cyst that is a result of the lymphatic system not forming properly, but no idea otherwise as no hard lump to be felt just soft swelling all on the left side of my face and neck, in the last two weeks I have also experienced numbness on that side of my face. Just wanted to know what the wait times people are experiencing for results. I also just hope nothing gets missed, I’m quite anxious and also work for a cancer organisation so it’s probably fuelling the fire whilst also telling me it is very unlikely to be cancer. I also haven’t been 100 percent the last four weeks ( which I’m putting down the numbness to possible infection of some form ) so probably just feeling a bit sorry for myself and fed up I’m not knowing what’s wrong - as even though this time periods been short the swelling has been around since last year and I actively ignored it because I passed it off as nothing. 

Any guidance on time lines or experience of mandible swelling would be grand haven’t found much from dr Google as other than mumps and broken jaw there isn’t much out there and well, it’s not mumps!!
