Just today I had noticed that there a bump or something like it on my left cheek near my jawbone. Its almost like that i will have to make it stay sometimes in one spot and not know where it is. It doesnt feel that big at all..very small and wish to know what exactly it is as far as something serious. I haven't had any symptons at all the only thing i can think of is that I have been washing my mouth with hydrogen proxide and salt mixed separately with water to help with my gums bleeding a lot.
