There is no better lesson about pain and suffering than that which our Lord Jesus Christ just prior to His cruxifiction. When we ask "why" the innocent suffer diseases or are victims of unimaginable atrocities, or ask "why me?!" lets always remember what God's only Son had to endure - for OUR salvation.
When we ask "What kind of God allows such horrors?!", always remember that it's the "kind" that offered His Lamb to be slaughtered by mankind as well.
"Why me?". Why not. We were never better than Him.
Christ had died. He had risen. And He will come again.
