Lump under chin in throat

Hi all!

I noticed I had a hard lump under my chin whilst putting on foundation. After a trip to the doctors I’ve been referred for a urgent scan and ENT. The lump is around 2cm

i have had several issues with tonsillitis in the past. My throat is sore, some chest pain and tonsils have swelled at the back of my throat. Other than that’s no other symptoms.

im starting to get really worried about the lump, it’s hard and I can help but google the worst. Has anyone experienced anything similar any advice welcome! 

Have my scan next week and just waiting on blood results.
