Ingrown nail?

So I got my toes done about a month ago and I asked them to apply power on it because my natural nail was cracked. The person doing my toes agreed that it should have the powder and tip applied to it. I just took the nails off yesterday because it was hurting so bad. I did both my big toes with powder and nail tips, but only this one was hurting me. I removed them and I notice that the side where I cut close to, has swollen a little bit. I’ve watched videos on youtube about ingrown nails and then cut down to where it’s pushing into the skin. I tried to do that and clipped as much as I could but it still hurts and is still swollen.

Anyone experience this before or know anything I can do?
