Mackenzie Miller suffers from a rare disease called Complex Regional Pain Syndrome (CRPS). CRPS is a form of chronic pain that usually affects an arm or a leg. It typically develops after an injury, a surgery, a stroke or a heart attack. The disease is uncommon, and its cause isn't clearly understood. There is no cure.

Mackenzie's family has spent thousands and thousands of dollars towards medicine, wheelchairs, rehabilitation, and a service dog who costs 20,000 dollars alone. All funds collected from this GoFundMe will be put directly towards covering the cost of Mackenzie's service dog. 

The Miller family and friends thank you for all your kind donations, love, and support. Please share this with everyone and help Mackenzie's fight against CRPS.
