Hard moveable lump on jaw line

I have a hard moveable lump on my jawline, its been their 3 months and has slowly grown, in the last week its increased in size more, should i be concerned? 

  • All lumps should be checked after 2 weeks, without exception. Especially if they are growing or changing for the worse. Unfortunately, no one can tell you what it may or may not be. Only an in person appointment with a gp or dentist (if it's tooth related) can set you down the road of getting some answers.

    I get that's not what you want to hear, but google, these forums and any other site out there aren't diagnostic tools.
