I got two wounds not really deep on my leg.they were treated at the urgency care and got a booster for tetanus 8 hours after the cut. should i worry?

Not necessaraly: You sound like you had everything done that is worth doing. I would just pay attention to the wound site for signs of proper healing.Look at it a couple times a day and look for swelling, redness, oozing or other feature that would suggest an infection is setting in. It may swell minimally and hurt for a while, but the process should be less troublesome every day until it heals.

Doesn't sound like: you have anything to worry about. keep the wounds cleaned and covered.
