Pain and suffering?

how much should i ask for in my lawsuit for pain and suffering. i had a hairline fracture on my c-4 in my neck. and i had a collapsed disc in my back. i had surgery a disc replacement with fusion. the fusion didnt take all the way. and i am still in pain. down my legs and into my toes. my recovering from the surgery was very painfull due to a hematoma in my stomach behind my incision. and i got very sick and had to go back to the hospital twice.
