The body is covered with red spots?


This symptom has persisted for several years.
I wake up feeling normal, but after a while, red spots gradually appear around my chest, shoulders, and even the upper back.
They look like a patch or resemble acne, but they are not raised, do not hurt, and are not itchy.
They become more pronounced after exercise.

More Info


Persistent red spots on the skin can be a source of concern and discomfort, especially when they appear without any accompanying pain or itching. Based on the symptoms you've described, it seems that these red spots may be related to a few potential causes, and understanding these can help in determining the best course of action for treatment.

One possible explanation for the appearance of red spots on the skin, particularly in areas like the chest, shoulders, and upper back, is a condition known as pityriasis rosea. This is a common skin rash that often begins with a single large spot (herald patch) and is followed by smaller spots that can appear in a "Christmas tree" pattern on the back. While it is generally self-limiting and resolves on its own within several weeks to months, it can cause concern due to its appearance.

Another potential cause could be exercise-induced vasodilation, which occurs when blood vessels expand during physical activity, leading to increased blood flow to the skin. This can cause temporary redness or the appearance of red spots, especially in individuals with sensitive skin. If the spots become more pronounced after exercise, this could be a contributing factor.

Allergic reactions or irritant contact dermatitis could also be responsible for the red spots. If you've recently changed soaps, detergents, or skincare products, these could be irritating your skin and causing localized redness. It's essential to consider any new products you may have introduced into your routine.

Folliculitis, an inflammation of the hair follicles, could also present as small red bumps that resemble acne. This condition can be triggered by various factors, including friction from clothing, sweating, or bacterial infections. If the spots are clustered around hair follicles, this might be a likely cause.

In terms of treatment, it is crucial to first identify the underlying cause of the red spots. Here are some general recommendations:
1. Avoid Irritants: If you suspect that a product may be causing the irritation, discontinue its use. Opt for gentle, hypoallergenic skincare products.

2. Moisturize: Keeping the skin well-hydrated can help reduce irritation and support the skin barrier. Look for non-comedogenic moisturizers that won't clog pores.

3. Cool Compresses: Applying a cool compress to the affected areas can help soothe the skin and reduce redness.

4. Topical Treatments: Over-the-counter hydrocortisone cream may help reduce inflammation and redness if the spots are due to irritation or mild dermatitis. However, it’s advisable to consult a healthcare provider before starting any new treatment.

5. Consult a Dermatologist: If the red spots persist or worsen, it is essential to seek professional medical advice. A dermatologist can provide a thorough examination and may recommend treatments such as topical steroids, antihistamines, or other medications based on the diagnosis.

6. Lifestyle Adjustments: Consider adjusting your exercise routine or clothing to minimize friction and sweating in the affected areas. Wearing breathable fabrics can help reduce irritation during workouts.

In summary, persistent red spots on the skin can arise from various causes, including skin conditions, exercise-related changes, or allergic reactions. Identifying the specific cause is crucial for effective treatment. If the symptoms continue or if you notice any changes in the appearance of the spots, it is advisable to consult a healthcare professional for a comprehensive evaluation and tailored treatment plan.
