Pain at its finest!

My pipes are secure but water leaks out, the dimension of an unveiling spout....

 I bear you pain, for I am your friend, but our last handshake won't grip until the very end, agony is what pumps the blood in my veins, as its tracks leave on my soul great stains...

 I'm capable of hiding, yet my strength is revealed to its residing, if known to me, the very vintage point lightining that is of struck...

I will eat of its dextirity, lest my soul hinder in fear or duck!
