I'm sorry to hear you're experiencing itching and small bumps on your body. These symptoms can arise from various causes such as allergic reactions, skin infections, insect bites, or side effects of medications.

Since you might be taking medication for diabetes, it's important to consider that some anti-diabetic drugs can occasionally cause skin reactions. Additionally, diabetes itself can increase the risk of skin infections and other skin issues.

Here are some general points to consider:

• Allergic reactions to new products, foods, or medications can cause itching and bumps.
• Skin infections (bacterial or fungal) may present with itching and bumps.
• Dry skin or irritation can also lead to these symptoms.
• If you recently started or changed any medication, including anti-diabetic drugs, this could be related.

Given the variety of possible causes and the need for a precise diagnosis, I strongly recommend consulting a dermatologist or your treating doctor. They can examine your skin, review your medications, and possibly perform tests to determine the exact cause and provide appropriate treatment.

If you experience worsening symptoms, signs of infection (such as redness, warmth, swelling, or pus), or systemic symptoms like fever, seek medical attention promptly.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
