The rash often covers large areas of the body and can cause swelling.
Systemic contact dermatitis can develop after a bout of allergic contact dermatitis.
Complications
Most cases of contact dermatitis do not progress or cause serious health issues.
That said, there is a small risk of complications.
Infection
The most common complication of contact dermatitis is infection.
Post-Inflammatory Hyperpigmentation
Contact dermatitis can lead topost-inflammatory hyperpigmentation.
This is darkening or discoloration of the skin due to an inflammatory response.
You’ll notice the discoloration after the contact dermatitis has healed.
Some cases of post-inflammatory hyperpigmentation fade away on their own over time.
Others can be permanent.
If the rash is healing well and isn’t too uncomfortable, there’s no need for medical treatment.
Still, it can be a frustrating problem to have.
The itching, burning, and discomfort can impact your life, even if it’s short-term.
The good news is that contact dermatitis can, in most cases, be easily treated.
Home remedies like oatmeal baths and cool compresses may also help.
Oral steroids may also be prescribed if the rash does not respond to topical medication.
