Rashes, or areas of itchy, swollen skin in the body, can be highly uncomfortable, with varying signs and symptoms, mainly depending on the trigger. While in some cases, skin conditions like atopic dermatitis (eczema) and psoriasis may trigger rashes, they might also be caused by other problems, such as stress, allergic reactions, and insect bites. Although rashes are not life-threatening, one should identify their signs early and consult a dermatologist for timely treatment.

Causes
Some of the common causes of a rash are:

• Chemicals in beauty, sanitary, and cleaning products like detergents, soaps, and creams
• Dyes and paints used in clothing
• Chemicals in rubber, latex, or elastic products
• Poisonous plants like poison oak, poison sumac, or poison ivy
• Prescription treatments
• Insect bites like mosquitoes, ticks, and other bugs
• Underlying bacterial infections or diseases

Rashes can occur in a few minutes post the reaction or as a slow build up over a period of time. Observe the rash and depending on the itching, pain, or appearance of the rash you can immediately see a doctor to find the cause of the rash. If it reduces within a day or two then it is likely to be a reaction to a medicine or chemical, however, if it persists and doesn’t go away for days then it could be a bigger problem.

Common rashes and how you can identify them

1. Contact dermatitis

Insect bites like mosquito, ants and bed bugs often itch and cause pain as well. You need to visit a doctor if you have bites of spiders, TseTse flies or Fire Ants to rule out any further poisoning.

3. Fungal infection
