Sometimes people are forced to endure the worst pain of their lives on a daily basis.

Our latest Everyday Hero suffers from a rare, painful disorder but it doesn't stop him from helping others.

John Miller is one of the most beloved donors at the One Blood Brandon Donor Center. He has a medical condition called neuro fibromatosis that causes tumors to develop on his nerve endings.

Yet he has donated 111 gallons of blood and counting. He said the pain he feels has nothing to do with a needle.

"Laying on my back, tumors on nerve endings as I lay here," he said. "I can't obviously get up and walk around every 5 or 10 minutes so, you know, you feel pressure on nerve endings."

His first blood donation was almost 25 years ago. He was given a red heart to wear, showing that he was a donor.

"So I had the heart thing on my vest at work and a little girl, maybe 4 or 5, just grabbed my leg and started squeezing and said, 'He gives blood for me.' And of course my heart went 'oop.'"

That little girl's mom explained to Miller that her daughter was ill and in need of many blood transfusions.

It turned Miller from a one-time donor to a life-long one. He is fantastically loyal Green Bay Packers fan and is involved in many volunteer activities.

One Blood's Daniel Eberts is one of Miller's fans.

"Hundreds and hundreds of lives and families have been saved or sustained by John's gift over these many, many years," Eberts said. "John is truly a silent hero."

Miller wears a cross related to the Trail of Tears given to him by a Native American friend. He was told it symbolized courage, endurance and strength.

That friend obviously knew John Miller.
