A skin rash becomes apparent if you see an unusual redness on your skin. Irritation, allergies, or inflammation could all be at blame. It can sometimes be handled on its own, but in extreme cases, you will need to seek medical attention to control the problem. They can be itchy, uncomfortable, and sometimes even unsightly. Most rashes are harmless and resolve on their own, but there are instances when they signal something more serious.
Common Types of Rashes
Hives
Hives are raised, red welts that often appear suddenly. They are typically caused by an allergic reaction and can be quite itchy and uncomfortable.
“Hives are considered skin allergies because they are triggered by an allergen. Following an allergic reaction, the body produces histamine protein, which causes capillary fluid leakage. This fluid accumulates, resulting in a raised, red, and irritating rash,” said Dr Ajay Rana, is an internationally renowned Dermatologist, Surgeon, Aesthetic Physician and the Founder & Director of ILAMED & Dermalyn Aesthetics.
Contact Dermatitis
This rash occurs when your skin comes into contact with an irritant or allergen. t's often itchy and red, and it can happen after touching substances like poison ivy or certain chemicals.

Heat Rash
Heat and humidity can lead to this type of rash. It manifests as tiny, itchy bumps and usually occurs in areas where sweat gets trapped, such as the folds of your skin.
Eczema
Eczema, also known as atopic dermatitis, is a chronic skin condition characterised by red, itchy, and inflamed skin. “People frequently underestimate skin eruptions, unaware that certain eruptions may be eczema, necessitating professional diagnosis and treatment. Unfortunately, many eczema cases deteriorate as a result of self-diagnosis and self-medication,” said Dr Hema Soujanya, Consultant, Dermatologist, Manipal Hospital, Vijayawada, Andhra Prades.
Psoriasis
Psoriasis is an autoimmune condition that leads to the rapid growth of skin cells, resulting in thick, scaly patches. It can be itchy and painful.
When to Seek Doctor Advice
While most rashes are harmless and can be managed with over-the-counter treatments or home remedies, there are times when a rash should raise a red flag:
