Skin Irritation after poking with needle

Hi,
   As you can read from the post yes i did make a mistake by poking something that was really nothing on my bottom chest. I thought there was something so i poked it and made it worse. It swelled up and was red. Now its been like almost 3 months the swelling did go down and the irritation too but not 100%....Still i feel like there is something in it, not like a hard bump but something clogged up...Here our two pictures of what it looks like and hope someone can adivse me how to treat this, hope it will go away...Thanks
