About a month ago now I was walking in my yard when I suddenly felt a sting on my leg and it was bleeding, I didn't worry because it was only 1 mark not 2 but now a month later it fully healed and there is a 2nd mark .5cm from it. Resembling a bat bite

Right now I'm feeling fatigued and have a runny nose but I'm getting a little better. I've talked to many people and they all told me I would've felt a bat on my leg way before it bit me, is this true? Or is there a chance I wouldn't have felt a bat there.
