What Could Be Causing Worsening Throbbing Pain, Redness, And Swelling In My Big Toe After Draining Pus?

I am having throbbing pain on the side of my big toe. Yesterday day it only hurt very slightly only when the area was touched. A tiny part of it was green, so I soaked it in Epsom salt and sprayed it with hydrogen peroxide twice. This drained the pus out but it still remained a little red and swollen. Everything went fine the rest of the day, but the throbbing pain woke me up tonight. It constantly hurts even when it is not being touched, and the redness and swelling is worse than it was yesterday. I am currently soaking it in Epsom salt. It is taking the edge off the pain. The swelling and redness have gone down alittle, but it is not giving full relief. The swollen area and the toenail hurts when touched. I pulled aside the skin and didn't see a hangnail and it seem like it is too far down the side to be an ingrown toenail.
