They look to me like ingrown hairs. Some people are more prone to them than others. I get one or two occasionally, but others may have more experience than myself. I think shaving against the grain , can in some ,cause them.
I had similar red bumps mate, I've started to use a product in the UK that contains 5% benzol peroxide after another member on here suggested it. It's cleared almost all of my red bumps and lumps up in 4 days.
I'll post before and after photos below...

Wow, very nice! What's it called?
In the UK it's called Acnecide.
It's made by a company called Galderma. I've cut down to using it just once a day and I will do until I run this tube out. Then I'll see if it comes back, if it does I'll probably book an appointment with a dermatologist but for now this has done the job.
