Itchy red bumps on the body are a sure sign of some kind of allergic skin reaction but then they are possibly also caused by a condition called keratosis pilaris. This is an odd condition in which a skin protein called keratin accumulates in the pores of the skin and this causes a reaction in the skin. Treating this condition requires that one continuously keeps the skin keratin free. Some of the most effective treatments for this condition are medical in nature and require a trip to the doctor’s clinic. There is another possibility that you are also affected with some kind of pathogen like the scalp fungus malessezia furfur. This fungus is what causes the very common condition called dandruff. It can affect other parts of the body as well. Dealing with this problem is much simpler than dealing with keratosis pilaris. The final possibility is that you are developing some kind of atopic dermatitis. This is mostly an allergic skin reaction that you need to control. Red bumps on the skin are a sign that the immune system of the body is at work trying to get rid of some kind of substance from the skin or trying to get rid of some kind of pathogen that has taken up residence on your skin. The redness is from increased blood flow to the site of infection that allows the red blood cells of the body access to the infection. In keratosis pilaris, the normal skin protein keratin is produced in huge and aberrant quantities that cause the keratin to harden up as it reaches the surface. This problem usually gets a lot worse during the months of the year when humidity levels are very low like winter.
Combating this problem requires removing the hardened plugs of keratin that have built up in your skin. This can be done by simply washing them off with some force. There are some simple face washes that you can use. For the next few months you need to wash your body with salicylic acid. This can break off the dead skin layers of the skin and the keratin plugs. This also requires some aggressive scrubbing. After you are done washing, use a tea tree oil containing body wash. Increase the amount of vitamin A that you consume from carrots and sea food or supplements. This problem could also go away by itself over a period of time.
