Three years old and as active as ever, you would never know Lewis Grensteiner is in remission from juvenile rheumatoid arthritis.
When he was about 15 months old, Lewis woke up and it "just seemed like he stopped walking," his mother Jill Grensteiner described.
"He was walking around with a stiff leg and we just really had no idea where this was going," she said.
For months Lewis had pain in his knee, finger, elbow and toes. His parents were in shock, wondering how can it be that such a young child suffered from arthritis. However, once he was diagnosed, he received joined injections a week later and was up and running the next day.
Relived, his parents realize Lewis is far from alone. According to the Arthritis Foundation, 300,000 children, many close to the same age as Lewis, suffer from juvenile arthritis. That's more than the number of kids dealing with diabetes, cystic fibrosis and muscular dystrophy combined.
Next Saturday, Lewis has been chosen as an honoree for the Arthritis Foundation's Walk to Cure Juvenile Arthritis at Mall of America.
As his parents point out, there's currently no cure for what he went through, and doctors remind the family any day the arthritis could come back.
"Thankfully, he is off his medication, and he is happy and he is healthy. We just pray this disease is something that we can look back on and say we are so blessed and so fortunate that it's something that is now behind us," Grensteiner said.
