Small painless bump on lip?

[LiyahS]

So, I have had this bump for multiple months. It is small and painless. It's not on the inside or along the lip line. It's on the upper lip only on the middle. I looked at many things to see what it may be before going to the doctor. Most things say symptoms will include, clusters, pain, swelling, and etc. I have not had any of that. It does not look like a cold sore or any std. I can just see it or feel it because it is hard. I thought it may have been an allergic reaction to chapstick because my lips have been more dry for months now. I had to switch chapsticks last year because I had tiny bumps that looked like a rash, but you had to be close to see. I switched chapsticks and it went away but then I see it again now with a bump. Can allergies happen without itching or swelling symptoms?

It could also just be a clogged pore or something of that nature- to know for sure what the cause is, you will need to have a doctor give you an in person exam and take the opportunity to gather more information on your medical history.  This is the only way to have an accurate diagnosis.
