The skin reacts to many different external stimuli, things like chemicals, lotions and sunlight, but it also reacts to things inside the body such as food and drink, so it can be quite a challenge to discover what in particular is causing red bumps on the skin. When red bumps are visible on the skin, people tend to ignore them, unless they itch of course. In this case, the irritation and discomfort can soon send people running to their health care professional for help, if the itchiness is severe, but finding the source of irritation can be a challenge.

Lice can cause red itchy bumps on the skin, with different types of lice found in different locations of the body. When the head itches it could be a signal that their are head lice present, and although it may be difficult to see the insects themselves, it is generally easy to see their eggs on the hair follicles. drug stores and pharmacies have special shampoos and combs to help deal with head lice. It should be noted that contrary to what people think, head lice do in fact like clean hair, whereas people often connect lice to poor hygiene.
Hives are also red bumps on the skin, but these raised marks are an allergic reaction to something, lotions, soaps, foods, clothing or medications. They typically do not last very long, and can be treated with hydrocortisone cream if they cause intense itching and discomfort.
For some people, exposure to sunlight can cause red bumps on skin. Polymorphous light eruption results in a red, itchy rash with red bumps clustered closely together. They typically appear a few hours after exposure to the sun, and generally are not found on the face, but occur on the chest, lower arms and legs. In some severe cases, this is accompanied with chills headaches and nausea. A few individuals are allergic to the light from the sun, and even a short time in sunlight can cause an allergic reaction with hives, and itchy red bumps on the skin. this condition is called solar urticaria, and can cause vomiting. For these conditions, it may be necessary to avoid sunlight, especially between 11 am and 3pm, and a strong sunscreen may also be necessary. For more severe cases, mild to moderate strength steroids may help to treat the red bumps on the skin caused by polymorphous light eruption, with oral steroids being used for severe cases. For those with solar urticaria, protecting the skin from the sun is the best bet, but should a rash appear, then keeping the skin away from more sunlight will be necessary, although antihistamines may help to reduce the itching and the red bumps on the skin.
There are many other conditions which cause red bumps on skin, like eczema and psoriasis, but these conditions need to be under the care of a medical doctor or health care worker.
