What should I put on my skin after a tick bite?

Tick . Topical corticosteroid reduces redness and swelling. If the area shows expanding redness or pain, see a dermatologist for evaluation and treatment.
Tick Bite. Most ticks do not carry diseases, and most tick bites do not cause serious health problems. The sooner ticks are removed, the less likely they are to spread disease. If a bite becomes irritated, apply an antibiotic ointment, such as Bacitracin or Polymyxin B sulfatte, and cover it with an adhesive bandage. The ointment will keep the bite from sticking to the bandage. If a rash, sore appears seedoc.
See a doctor. Since ticks carry lyme disease it is important to be tested for lyme disease and treated with antibiotics. A topical is not a treatment for an infection from a tick bite.
