Giant Cell Tumor

I have a giant cell tumor in my left knee. After I gave birth to my youngest child, I started to feel pain when I am walking. And because I don't have a job because I only gave birth, it's hard for me to get a check-up to the hospital. Then month after month, my knee became larger and larger. It's too late when someone gave me some money to go to a doctor. Then the result is that I already have a tumor. It's really hard for me because I have 2 children and the youngest is only 1 y.o. I can't even go to the bathroom without the help of my husband. That's why he can't even find a work because he's the one who takes care of me and our children. I am hoping that someone can help me financially so that I can go back to work for the sake of my children. Thank u very much!!
