What's Causing My Rash?

Generally, the term “rash” refers to a change in appearance or texture of one’s skin. This can happen for many reasons, and occur in many forms- bumps, scabbing, redness, marks, etc. Most rashes are fairly benign and no cause for worry, although in cases of severe discomfort, concurrent onset of other symptoms, or a rash that fails to go away on its own, you should consult one of the expert physicians at Long Island Medical & Cosmetic Dermatology.

Some Common Causes:

Eczema- A type of dermatitis, or skin inflammation, eczema has many different etiologies. From irritated dry skin to a local allergic reaction, eczema is a common rash pathology. Symptoms associated with eczema are usually limited to itching and patches of redness, although more severe cases can result in fluid leakage and crusting. Eczema, while uncomfortable, is not usually a sign of any more severe systemic condition. There is no complete cure available, but your dermatologist can help you treat the symptoms and determine if the cause is something avoidable, like contact with an allergen. 

Infections- A rash can be a sign of bacterial, fungal, or viral skin infections like ringworm, or impetigo. There are certain creams and topical methods of treatment for rashes resulting from infections which can attack the pathological organism. These should not be used with immune modulators like antihistamines or corticosteroid creams, as the effects will counteract each other. If you are unsure which treatment is right for you, consult your doctor.

Systemic Conditions- Sometimes, a rash can be a sign of a larger problem such as a systemic allergic reaction, as in the case of quickly appearing hives. Certain diseases also present with types of rashes, such as Lyme disease and scarlet fever. Autoimmune disorders can also result in rashes, such as psoriasis. If you believe that your rash is associated with an underlying condition, make sure you consult a physician to ensure proper diagnosis, as merely treating the symptoms of the rash may not be adequate. 

Treating Your Rash

Most rashes will fade on their own, and dermatologist-recommended lotions and ointments can help with discomfort and speed healing. If you can determine a cause like poison ivy, repeated contact with an allergen, or abrasive clothing, try to reduce and avoid the problem. If your rash gets progressively worse, you have other symptoms develop concurrently, or it does not go away within 2-3 weeks, make sure to get medical attention.
