You : You should see a physician to get the tick carefully removed. Some ticks are capable of transmitting disease, including lyme disease. The tick can be sent to a lab to determine the risk. You may need antibiotic treatment. Failure to treat an infectious tick bite can have long-term consequences.

Urgent care visit: Ok, if you can't reach it, then see a professional who can, and who can evaluate and decide if locally irritated / infected / lyme risk. Primary care or urgent care can usually deal with this.
