Last October, Ma Sam slipped on a road near her tent and injured her knee. She was unable to see a doctor at the time because she had no one to accompany her. She has since had surgery but is unable to afford the follow-up treatment she needs. Her knee is still swollen and causes her significant pain. Ma Sam is a single mother who currently lives with her daughters and mother-in-law, who help her with cooking and other household tasks. She works as a day laborer to provide for her children. "I hope to get treatment and be a healthy woman in the future," says Ma Sam. For $1,500, Ma Sam can receive the follow-up treatment she needs to support her family.
