Dealing with doctor's appointments and hospitals can be a very tedious and stressful process. Trying to find the right doctor or the right treatment, spending hours in traffic and waiting rooms—sometimes even weeks are spent trying a certain therapy, only for it to make things worse. The Chazon Ish wrote in a letter that it is a mitzvah to seek medical treatment, just like any other mitzvah. A person is obligated to take care of his health through natural means, and by doing so, he is fulfilling the will of Hashem. Therefore, when seeking medical treatment, one should feel as though he is performing any other mitzvah. He should even say לשם יחוד . He should feel that he is growing spiritually and keep in mind that he is doing this because Hashem commanded in the Torah: " ונשמרתם מאד לנפשותיכם " We are obligated to make hishtadlut for our health, to such an extent that even the sanctity of Shabbat is overridden in cases of danger. As the pasuk says: " וחי בהם " —You shall live by them. However, the only concern when engaging in hishtadlut is if a person begins to believe that the doctor is the one in control. We must never think that the doctor determines whether a person will actually be healed. That decision is entirely up to Hashem. If someone is meant to be healed, Hashem will grant the doctor the heavenly help needed to accomplish it. But Hashem doesn't need a doctor. He can heal a person with His words alone, as it says: " ישלח דברו וירפאם " Therefore, no doctor should ever say there is no hope. He can say that there is no known cure available at the moment, but with tefillah , Hashem can change anything. Hashem is the One who enables doctors to perform, and so our primary hishtadlut is always with Him. We can always be healed, no matter where we are or who is—or isn't—available to treat us. There is a man who shared the following story. He was in Ukraine on an outreach program, working to bring Jews closer to Torah and mitzvot. One morning, he woke up with terrible pain on the side of his head. A local doctor told him that the uppermost vertebra in his spine had moved out of place. The doctor added that surgery would most likely be required to fix it, but the procedure carried a very high risk of damaging nerves that could leave him unable to walk. The man immediately called his father-in-law, who was well-connected in the field of medicine. He described his pain and asked for urgent help. His father-in-law said he knew of an excellent doctor in Ramat Gan and would reach out to him. A short while later, the father-in-law called back and said, "The doctor from Ramat Gan is flying to your location tomorrow. He's going to treat you." The man couldn't believe it. How could this doctor be coming all the way to Ukraine? The next day, the doctor arrived. His treatment was almost miraculously quick and simple. No surgery was needed, and the problem was resolved. At the end of the visit, the man asked how much he owed. The doctor replied, "For my time, travel, and the procedure, it would be a large sum. But you don't owe anything. Two wealthy people who live nearby brought me here to treat them. My flight came in early enough that I had time to see you before my appointments. Hashem arranged for you to get top care at no cost. So the thanks go to Him." It was truly amazing. Hashem is the One in charge of every person's health. He sends the messengers He chooses to heal people, and He determines exactly when and how that healing takes place. We are obligated to take care of our health and to seek out the best messengers—but we must never forget that it is always only in the hands of Hashem.
