What to Do If You Have Strep Throat While Pregnant. Sore throats are a common symptom of countless ailments. Your throat may be irritated by allergies. You may have a cold or flu. Or, you may have just been using your voice too much. The most common cause of sore throat is strep throat. A reported 15 percent of sore throat cases are caused by strep.
Boils may be caused by a weakened immune system. When a child's immune system is weak, his body is unable to resist the attack of bacteria that cause boils. Children who suffer from repeated attacks despite taking precautions to not become infected with boils need to have their blood tested.
Boils (furuncles) can develop anywhere on your skin, but they're most likely to occur at the site of an infected hair follicle (a hole a hair grows out of). Boils most commonly develop on areas of skin where there's a combination of hair, sweat and friction, such as the neck, face or thighs. Over time, pus forms inside the boil, causing it to grow larger and become more painful. In most cases, a boil will eventually burst and the pus will drain away without leaving a scar. This can take from two days to three weeks to happen. Boils are more common in teenagers and young adults, especially in males.
