While lymphatic drainage is a beneficial and therapeutic technique, there are certain conditions where it should be avoided or done with caution. Contraindications include:

• Acute infections (as stimulating circulation may spread bacteria or viruses)
• Phlebitis and thrombophlebitis (risk of dislodging a blood clot)
• Active and diagnosed cancer (unless cleared by a physician)
• Heart failure (as the increased fluid movement may put extra strain on the heart)
• Arterial hypotension (low blood pressure, as lymphatic drainage may further lower it)
• Untreated hyperthyroidism (as it can stimulate the metabolism)
• Severe and untreated bronchial asthma (to avoid triggering respiratory distress)
• Fever or systemic infections (as lymphatic stimulation could worsen symptoms)
• Pregnancy under 3 months (as a precaution, unless approved by a healthcare provider)

If you have any of these conditions or concerns, it is essential to consult with your doctor before receiving lymphatic drainage to ensure it is safe for you.
