It's understandable to feel uncertain about a rash, especially in a hot climate. While many rashes are benign, the description you provided indicates that closer monitoring is needed, particularly since the bumps have increased in size over time.

Explanation: Rashes can arise from various causes, including heat rash, allergies, insect bites, or even infections. The fact that the bumps are not itchy or painful is a positive sign, but the growth of the rash is concerning. The cluster of larger bumps may suggest a need for evaluation to rule out any infections, skin conditions, or allergic reactions.

Prioritized Next Steps:

1. Observe Changes: Keep an eye on the rash over the next few days. Note any changes in size, color, or if new bumps appear. This information can be helpful later.

2. Avoid Irritants: Stay away from harsh soaps, fragrances, and other potential irritants on the affected skin. If you use any topical products or medications, consider stopping them until the rash is evaluated.

3. Soothing Care: Applying cool compresses to your arm may help soothe the area, especially in hot weather. Ensure you're also staying hydrated.

4. Monitor Symptoms: Be vigilant for any new symptoms such as itching, pain, blistering, or weeping from the rash, as these may indicate a more serious issue that would warrant immediate medical attention.

5. Consider Timing for Doctor: While it may not be necessary to see a physician immediately, plan to schedule an appointment if the rash does not improve or continues to grow over the next week, or if new concerning symptoms develop.

By taking these steps, you can monitor the rash effectively and identify if professional care is needed soon. Remember, it's always best to err on the side of caution with skin changes. Please let me know if you have any more questions!
