I'm sorry to hear about the infection and rash you're experiencing. These symptoms can have various causes, and it's important to get a proper evaluation to determine the exact cause and appropriate treatment.

Here are some general steps you can take:

• Avoid scratching or irritating the affected areas to prevent worsening or spreading.
• Keep the areas clean and dry. Use mild soap and water to gently cleanse the skin.
• Avoid using any over-the-counter creams or medications without consulting a doctor, especially on sensitive areas like the genital region.
• Since you have symptoms in two different areas (penis and hand), it is important to see a dermatologist or a urologist for a thorough examination and possibly some tests to identify the infection type (bacterial, fungal, viral, or allergic reaction).

Regarding medication, antibiotics like Cefadrox (Cefadroxil) are prescription drugs used for bacterial infections, but they should only be taken after a doctor confirms the infection type and prescribes the correct dosage.

Please consult a specialist doctor promptly to get an accurate diagnosis and safe, effective treatment tailored to your condition. If symptoms worsen or you develop fever, pain, or spreading rash, seek medical attention urgently.To narrow down potential causes, we will need some more information.I understand you're dealing with a penis infection and a rash on your hand.
