Why Have I Had Small Red Swollen Lesions In My Mouth For A Few Weeks?

Hi I have had these small red lesions in my mouth for a few weeks. They are only on the inside of my cheeks. 5 on one side and 3 on the other. No pain at all. Then there is a big red spot that is puckered and slightly swollen. I have looked up everything I possibly could and nothing on the internet looks like what I have. No swollen lymph nodes, no fever, I don t feel sick. I have tried to weed out any possible things that could of caused this to happen, I just quit smoking my electronic cigarette device today because I think that is the culprit. Please let me know if there is any way I can send some pictures of the inside of my mouth so you can see what it may be.
