Is it normal I feel that tattoo's are overdone these days

I got my tattoo about 5 months ago and it has been getting a lot of little pimples on and around it. They are on my arm and it itches and bugs. I got it at my friends house and I made sure all the tools were clean. I did get a fever once a week after getting it but that was it. Pimples have been on and off, but now it just got a lot of these and now it makes me wonder if it could be an infection.
