WHAT IS THIS???? ON MY NIPPLE?

I notticed this about two days ago

Hi J, Looking at it, I would say nothing, but come back if it gets a lot bigger.

Okay tnx

Looks like blocked pore or blackhead. 

Is that something serious or it will disappear on own?

 Hi J, You have had it 5 years and now your worried?

I dont understand i didnt know i have it

I have a sebaceous cyst almost on the same spot , It's harmless but I have to squeeze it empty occasionally

As pattino says, you may need to squeeze it.

I will try

I tried and it wont move for a bit

Probably best, then, to leave it alone and see what / if anything develops. 

Okay

My sebaceous cyst is actually bigger than your "thing" , Tomorrow I'll try to post a pic of my cyst so you get the idea of the difference.

what you have doesn't seem like anything to worry about ,it's very small.

Thank you i will wait for photo

Before and after the squeeze

Mine is so much smaller and thry are not even similar, nevermind i appreciate your help
