Medical regulations state that "a physician must personally examine a patient before administering treatment or prescribing medication..." Therefore, online diagnosis is also not permissible.
If you are experiencing significant distress, it is advisable to seek medical attention promptly.

More Info


Understanding skin bumps can be quite challenging, especially when they appear suddenly and cause discomfort. Based on your description, it seems you are experiencing round, raised bumps on your skin that are painful to the touch. While I cannot provide a definitive diagnosis without a physical examination, I can offer some insights into potential causes, treatments, and care tips for skin bumps.


Possible Causes of Skin Bumps
1. Folliculitis: This is an inflammation of the hair follicles, often caused by bacterial or fungal infections. It can lead to small, red, pus-filled bumps that may be itchy or painful.

2. Sebaceous Cysts: These are non-cancerous lumps beneath the skin, often filled with a fatty substance. They can become inflamed or infected, leading to pain and swelling.

3. Allergic Reactions: Skin bumps can also result from allergic reactions to substances such as soaps, detergents, or certain foods. This can cause hives or localized swelling.

4. Insect Bites: Bumps that are itchy and painful could also be the result of insect bites, which can cause localized swelling and irritation.

5. Dermatological Conditions: Conditions like eczema or psoriasis can lead to raised bumps on the skin, often accompanied by redness and itching.


Treatment Options
1. Topical Treatments: Depending on the cause, over-the-counter topical treatments may help. For example:
- Hydrocortisone Cream: This can reduce inflammation and itching if the bumps are due to an allergic reaction or mild dermatitis.

- Antibiotic Ointments: If you suspect a bacterial infection, applying an antibiotic ointment like Neosporin may help prevent further infection.

2. Oral Medications: If the bumps are painful or if you suspect an infection, consulting a healthcare provider for oral antibiotics or antihistamines may be necessary.

3. Warm Compresses: Applying a warm compress to the affected area can help reduce pain and swelling, especially if the bumps are inflamed.

4. Avoid Picking or Scratching: It’s crucial to avoid picking at the bumps, as this can lead to further irritation or infection.


Care Tips
- Keep the Area Clean: Gently wash the affected area with mild soap and water to keep it clean and prevent infection.

- Moisturize: If the skin is dry, using a fragrance-free moisturizer can help soothe irritation.

- Monitor Symptoms: Keep an eye on the bumps. If they worsen, spread, or if you develop fever or other systemic symptoms, seek medical attention promptly.

- Avoid Irritants: Identify and avoid any potential irritants or allergens that may have triggered the bumps.


When to Seek Medical Attention
If the bumps persist for more than a few days, increase in size, or are accompanied by fever, significant pain, or drainage of pus, it is essential to seek medical attention. A healthcare provider can perform a physical examination and may recommend further testing or treatments based on the specific diagnosis.

In summary, while there are various potential causes for skin bumps, appropriate treatment and care depend on the underlying issue. If you are unsure about the nature of your skin condition or if it is causing significant discomfort, it is advisable to consult a healthcare professional for a thorough evaluation and personalized treatment plan.
