No. Warts don't come on suddenly in so many different areas (head, shaft, etc.) They don't look like scabbed bumps either. I guess they're probably clogged pores from friction, perhaps scabbed from picking. But to really know what they are, I suggest you see a doctor and that you do it soon, not because I'm afraid they're bad news but because if you wait till they disappear, the doctor won't be able to do more than guess at what they are.
Best.
