Came Back Inside With What Looks Like a Bite

Yesterday I went out back to make a call and was walking around the yard while I talked. Fast forward to when I get back inside and there is blood coming down my leg then after I clean it up I see this.

I didn't see any animal and the injury was towards the top of my shin (didn't feel anything either). Since I'm prone to anxiety about rabies i started panicking and have been really anxious since it happened.

Don't know if I'm being ridiculous here or I should go to an urgent care.
