Raising money for dad’s treatment

My dad has been fainting since last week. We got him checked up and the doctor said he has epilepsy. However, the medications he prescribed couldn't resolve the issue. We saw another doctor and he prescribed MRI and ECG. We are a middle class family and only my dad worked. Now he is not able to work properly and with my sister's education and other debts and expenses, things are overwhelming for him and for us. He needs these tests urgently. And I couldn't arrange the money needed. Hence, Please help me out this once.
