There are a number of different viral infections that may result in a rash depending on the situation. However, you may also be describing what is commonly referred to as prickly heat, a rash that typically comes about when the sweat glands are activated but become partially blocked due to dead skin cells or bacteria. The resulting rash is itchy and raised and can last for a very short period of time or for several days. If this is the case, cooling the skin with water or some fresh aloe, or R-Pur Aloe liquid, may help to reduce the symptoms. Using a natural exfoliant like E3 Liveโ€s Light Polish may help to keep the affected areas clean and remove dead skin cells more effectively. Further, I would suggest using products, skin products, shampoos, detergents, and soaps that are made from natural ingredients that, for the majority of people, tend to cause fewer allergic reactions and to leave less synthetic residue on the skin to block sweat glands.

It is also possible that some of the toxins stored within your system are being excreted through the skin and causing a reaction. For most people, this can be addressed by starting with a colon cleanse, performing 2-3 back-to back liver and gallbladder flushes and then a parasite cleanse. The following links describe this process in greater detail:

Further more a bioflavanoid supplement with high levels of quercetin, preferably quercetin chalcone if you can find it, along with a vegetable-based enzyme like Zymitol can help to control histamine levels, which should help to reduce the itching and swelling of a rash or allergy.
