I need help finding this out

So there was a small pimple like bump on my penis shaft and I squeezed it thinking it would pop it didn't and it started to pain now it's gotten bigger is there day see for concern?

THE thing to consider is whether you are sexually active or not, and if so whether you recently had unprotected sex or not, and / or, whether you have ever had an Herpes outbreak or not?
For most spots and pimples that appear on the penis I use liquid Antiseptic and as long as you keep the area clean, use the antiseptic 3 or 4 times a day it should clear away within 4 or 5 days - if not, see a doctor …
