Should I go to urgent care?

I hit my head at work the other day. It's quite funny how it happened but after I hit my head My vision went blurry for a few seconds and i had laid down in the floor for a few seconds and I blew it off and went right back to work. I went home and I had a blistering headache and I was exhausted so I took a quick nap and some of my prescribed migraine medicine. That seemed to help and for the past few days I've been taking them every 6 hours as said on the bottle to keep the pain mild. (I never need to take more than one a day if I just have a usual migraine) and today, I woke up feeling like someone had put glass shards in my head and shook it as hard as they could. I was told to only worry if I blacked out and I never did and if the mark on my head was a dent instead of a knot and it's definitely a knot. It's also very sore and it bled a little bit. If I get medical attention I feel like they'll just tell me well you have a cuncussion go home and rest and that's what I've been doing, seriously all I've been doing is laying around because my head hurts. Should I go get it looked at? What's the worse possibility If I don't go?
