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.
The severity of an insect sting reaction varies from person to person. A normal reaction will result in pain, swelling and redness confined to the sting site. Simply disinfect the area (washing with soap and water will do) and apply ice to reduce the swelling. A large local reaction will result in swelling that extends beyond the sting site.
