Asking financial help to treat cellulitis.

I am fighting with cellulitis since four months and two third of my right foot had been cutting out. I have spent more than thirty Lac taka for my treatment. But doctor said if I want to save my leg I have to take medical proper support for more than eight months. During this time I have to regularly dressing the wound by medical professional. I have to take higher antibiotics, surgical items and small surgeries. I have to stay at hospital untill the infection will come under controlled. To save my leg I need more than 3500000 taka except skin grafting. Now I am empty and totally unable to continue my treatment. I want to save my leg. Would you please help me to survive??
