A large, red pimple suddenly popped up on my cheek. Do I need to get an injection? ㅠㅠ

Maybe it's because the weather has been so hot and humid lately, but when I washed my face and looked in the mirror this morning, a red pimple suddenly popped up on my cheek just like in the photo ㅠㅠ It hasn't turned yellow or festered yet, but it feels hot to the touch and hurts a bit, so I'm super stressed out haha. I'm worried that if I squeeze it out with my hands, it will definitely leave hyperpigmentation and a scar. In a situation like this, would going to a dermatologist to get an injection to reduce inflammation be the fastest way to calm it down? Or I'm really torn between getting a laser to kill acne bacteria or getting overall sebum control treatment ㅠㅠ Please give me some tips,先輩s! What kind of treatments do you usually get when pimples start popping up one by one? Does an injection make them go down immediately the next day? I really need to decide tomorrow whether or not to go to the doctor right away ㅠㅠ
