Moles are normal, and moles popping up are normal as you get older (the more your in the sun the more moles you will see) but its nothing to get concerned with UNLESS THEY START TO BOTHER YOU- if they start to hurt, become abnormally hard, or irritate you- then you need to get them checked out. if they are just normal moles (not growing in size) and they dont bother you, you are fine. but again if they start to get bigger, harder, or painful then you need to get them checked out- sometimes if moles become irritated and hurt you they turn out to just be ingrown hairs, but it could always be something else. thats why i said if they start to grow, get hard, or irritate you to get them checked out either way. if they arnt doing any of those things- you fine.
