Tipping is not a common practice in the medical field and is generally not expected or appropriate for doctors or healthcare professionals. In many countries, including the United States, doctors are well-compensated for their services through various means such as insurance reimbursements, government funding, or direct payment from patients.
Thanking a doctor for their help and expressing gratitude is certainly appreciated and encouraged, but this is typically done through words or a heartfelt thank-you card rather than a monetary tip. Most doctors enter the medical profession to help people and improve their patients' health, rather than for financial gain or tips.
If you feel particularly grateful for the care and treatment you received from a doctor, a simple and thoughtful thank-you note can go a long way in showing your appreciation for their hard work and dedication. Alternatively, if you wish to express gratitude in a more tangible manner, you can consider making a donation to a healthcare-related charity or a medical research institution in their honor.
Ultimately, the most important thing is to show genuine appreciation and respect for the doctor's expertise and the care they provided during your illness.
