I have 3 bites on my leg. red center then white and then red. they itch a lot?

For bug bites...: For bug bites, one can take over-the-counter claritin, zyrtec, or Benadryl (diphenhydramine) to block histamine, which causes itching. Putting Hydrocortisone 1% cream 2-3 times a day on the bites for 3-4 days may help them go away. For more itch relief, one can add an anti-itch gel such as "itch-x" on the bites. Itch-x has an anesthetic to numb the itch. If bites are growing or painful, a doctor should evaluate.
