Got a minor bump on the head yesterday and i'm paranoid it'll turn into something worse.

Yesterday I accidentally bumped the top of my head into the corner of a wooden cabinet. it was only a minor bump(as the pain went away in less then a minute and it wasn't bleeding or anything) and i'm paranoid that I mighty have a concussion or worse. I looked it up and I don't have any of the symptoms but I still can't help but be paranoid. Especially today now that spot on my head that got head is now slightly sore to the touch when I didn't feel anything when I touched it there yesterday(unless I somehow missed touching that spot yesterday)I looked up similar cases of people worrying over bumps on heads and i'm trying to tell myself it'll be OK but I still can't help but worry, last night I had some trouble getting to sleep(As I was worried something bad might happen to me in my sleep)and i'm sure i'll have trouble again tonight. Does not feel like there's any swelling(though the spot on my head that got hit is covered up by hair so it's a little hard to hell)so i'm wondering if I should put ice on it.
