Back pain (lumbar region) Least 4 days.

I have been having backpain since after my delivery.i feel pain in my back immediately after standing for half an hour.i can't sit or can't bend after standing for long time I.e more than 20min. I feel my back was stiffened if I try to sit. The same way, I can't stand immediately after sitting for long time. my back is not supporting.it takes minimum 5 minutes to set right my back. I can't lie down left side. if I try so, I feel pain in right side of the back. Can't bend in some postures.if I try to bend back, while combing my hair, I feel that my back is broken.i can't see upright position while the backpain persists. I can't hold anything tightly with my hand.if anything hits my arm, my arm turns into green and having pain for at least 4 days. I consulted an ayurvedic doctor and he said that I have issue in lumbar region. Please suggest me to get out of the pain.
