How quickly does microwave sweat gland treatment relieve excessive sweating?

Microwave energy is delivered to the underarm to heat and affect sweat glands. The area may feel swollen, tender, numb, or lumpy while it heals, and these sensations can make early assessment difficult. Sweat reduction may become noticeable before all local swelling has settled. The response is specific to treated underarms; sweating elsewhere, such as the hands, feet, or face, is not expected to change from an underarm treatment.

Use cooling and pain relief only as advised by your clinician. Keep the underarms clean, avoid rubbing or shaving until instructed, and wear loose clothing while the skin is sensitive. Keep a simple note of dampness, clothing changes, and activities so you can compare progress after recovery. A review appointment helps assess whether the response is developing as expected and whether another plan is needed.

Call the clinic if pain, redness, warmth, swelling, or drainage is increasing, or if you develop fever, marked skin changes, or weakness in the arm. Seek prompt advice for persistent numbness or severe tenderness. New sweating with chest symptoms, faintness, or feeling acutely unwell needs urgent medical attention rather than a routine treatment review.

Ask which changes are expected during healing, when to measure the result, how the treatment affects underarm sweat glands, what to do about sweating in other body areas, and when a follow-up is appropriate.
