How can I make my skin stop throbbing?

I do not have infections. My mom and dad caught me having sex in the garage around 2 am. They were gone all day and night and I didn't wanna risk car sex or something. So my dad dragged me in and I was beaten with a belt and my mom is talking about a restraining order on my boyfriend. I don't have a phone anymore so I am using my tablet. This all happened 2 days ago but my skin on my thighs is still throbbing from the hits and I don't know how to stop the irritation. I have used pain pills, I was told to soak in warm baths and I did but nothing is really working. What can I do to fix this please, it is really uncomfortable and I can't wear tight fitting pants at the moment
