Throbbing big toe week after toenail fell off.?

Monday of last week I had a toenail clipped off. It was already almost completely detached so I didn't have any torn or ripped off. No bleeding whatsoever. The doctor said it looked like it was caused by a blister under the toenail from shoes or running. My toenail already has about 3 months of growth (it was growing with my old nail on top of it because I didn't know it was falling off) but just last night, I was woken at 3 AM by throbbing toe pain. My boyfriend said he thinks it's because I still have some of my old toenail attached in the corners and maybe the new nail is trying to push it away? But I've never felt this sort of pain in my toe before. It's red, swollen, warm to the touch and tender all around. Swelling starting from then "knuckle" of my big toe? I've already decided if it's still this bad after work today I'll call my doctor, just wondering if this has happened to anybody else? Or know what could be causing it? I don't usually get sick or hurt so I'm not sure if I'm overreacting, but I have a few tattoos and piercings and feel like I manage pain well. Thanks!
