A red, pimple-like bump suddenly appeared on my cheek. Do I need to get an anti-inflammatory shot? ㅠㅠ

Maybe it's because the weather has been hot lately, but when I washed my face and looked in the mirror, a red pimple had suddenly popped up on my cheek, just like in the photo ㅠㅠ It's not really festering or super painful yet, but it feels warm to the touch, and it's subtly bothering me, so I'm getting stressed out haha. I'm worried that if I squeeze it, it will definitely leave a scar and cause hyperpigmentation. In this case, would going to a dermatologist to get an anti-inflammatory injection be the fastest way to get it over? Or should I just apply acne ointment and watch it for a few more days? I'm really torn ㅠㅠ Please share some dermatology tips on how you all deal with these ambiguous red blemishes popping up one by one like this! I have to decide tomorrow whether or not to go to the dermatologist, so I urgently need your advice haha.
