Reduced pulses in feet can signal heart disease risks. Peripheral artery disease (PAD) is a buildup of cholesterol and plaque in the arteries that lead to the extremities. PAD can cause discomfort in your legs and feet, limit your walking and activities, or severe PAD can progress to loss of limb. Your doctor can check for signs of the disease with a simple test of pulses in your feet.
1 An antihistamine taken by mouth, such as Benadryl or Chlor-Trimeton, may help relieve itching, redness, and swelling. Don't give antihistamines to your child unless you've checked with the doctor first.  A spray of local anesthetic containing benzocaine, such as Solarcaine, may help relieve pain.
Wash the affected area with soap and water, then apply ice or a cold pack to reduce pain and swelling. Other treatments for mild insect stings: Elevate the arm or leg. (However, with venomous spider and scorpion bites, do not raise the site of the bite above the level of the victim's heart.) Apply a cold compress.
