Everything you’ve been trying to find out about that pimply rash


There are many different problems that can cause a red, pimply, rash, so it’s important to look at all of the symptoms when you’re trying to determine the best treatment.  As with any rash, it’s always a good idea to see your doctor, even though many rashes are not cause for significant alarm.


One of the most common causes of a pimply rash is a heat rash.  The rash could appear on the neck, chest, stomach, back, under the arms, or behind the knees.  It commonly appears in parts of the body that either rub together or are rubbed by the edges of clothing.  Heat rash is especially common in people who have been sitting in direct sunlight for a while, or those who are in a room that is too warm.  Heat rash is more common in children than adults.  The easiest way to get rid of heat rash is to move into an air-conditioned room that has proper ventilation.  Wearing lightweight clothing can help prevent heat rash.  Most cases of heat rash don’t really require any medical attention, although in very severe cases, the best course of action is to apply calamine lotion.  Even more severe cases may require lanolin lotion or a topical steroid cream.


Another very common cause of a pimply rash is a food allergy.  Usually there are a whole host of other symptoms that occur along with a pimply rash if a food allergy is causing the problem.  Other symptoms of food allergies include itching, swelling of the lips, face, tongue, and throat, difficulty breathing, and even abdominal pain, diarrhea, nausea, and vomiting.  Extremely severe cases of food allergies can also cause anaphylaxis, which can be fatal.  Anaphylaxis is characterized by tightening of the airways, shock, a severe drop in blood pressure, and rapid pulse rate. 

The only way to avoid experiencing symptoms of a food allergy is to completely avoid the food that’s causing the problem.  It may be very easy to figure out which food is causing the allergic response if you’ve eaten something new lately, but it can be more difficult if you’re trying to determine which food caused the allergic response in a baby.  Doctors will usually tell you which foods are the most likely culprits, and you will want to eliminate all of those things from your baby’s diet.  From there, you can slowly add one food back into the diet at a time.  This way you’ll know for sure which food is causing the allergic response.


Scarlet fever can also cause a red, pimply rash.  The rash looks very much like sunburn, although it feels very rough like sandpaper.  The patient will also experience many other symptoms if scarlet fever is what’s causing the rash.  Other symptoms include red lines in the folds of skin around the groin, armpits, elbows, knees, and neck, a red and white, bumpy tongue that looks like strawberries with a white coating, and a very high fever.  Immediate hospitalization is likely necessary for patients with scarlet fever.
