Been there done that. Save the tick and bring it to your docs so they can send it away for testing (I put mine in one of those little ziplock bags that an extra button comes in). The tick I had was slightly larger than a fleck of pepper and they can't get conclusive results from testing something that small. The one I had was 60% +/- chance of carrying Lyme disease so they treated me with antibiotics to be on the safe side. All I had to pay was my doctor's visit co-pay.
