My wife is the kind of person who rarely flinches in the face of pain. When she gave birth, she didn’t shed a single tear. Once, she put an electric screwdriver bit through her thumb and only calmly said “ouch” as blood ran down her hand. To say she has a high pain tolerance is an understatement.

But for the past several days, I’ve seen her cry in agony. Her knee, swollen and unbearable, felt as if someone was relentlessly striking it with a ball-peen hammer. When her oncologist saw her on Monday morning, I could see the sorrow in his eyes—35 years of service, and he had never witnessed something like this. Her knee was so swollen that he immediately decided to admit her and called in an orthopedic surgeon to review her MRI. Despite everything from Tylenol to a Methadone drip, nothing could touch the pain.

The next morning, without anesthesia, the surgeon withdrew a yellowish fluid from her knee. It was the first relief she’d felt in days. A few hours later, the palliative care physician switched her to a morphine drip, and finally, her pain was brought down to a manageable level. Unfortunately, the damage was already done—the fluid had put so much pressure on her knee that it cut off the blood supply, causing part of the bone to die and partially fracture.

Now, my little warrior hops to the bathroom and back to her bed. Her third round of chemotherapy didn’t work, and tomorrow she’ll begin her fourth type through a second port after the first one became infected and had to be removed. It feels overwhelming, insurmountable at times, but she keeps smiling through the tears.

We are surrounded by love—family, friends, co-workers and even strangers send prayers, food, flowers, and help get her to appointments. No one is giving up on her. Even though she sometimes says she can’t go on, she does. We love her so much, and her strength and resilience continue to amaze us all.

She is a testament to the human spirit’s ability to endure, and no matter how impossible the battle may seem, we are all standing by her side. She fights, she smiles, and we love her more every single day.
