Medically why do our body's ache so much?

Annie,
Thanks for the call
I will try to call you this week
Have been feeling really poopy these last few weeks and don't like to talk when I'm down.
I wish you a peaceful recovery, Annie
Please take your recovery slowly.
Us type A's just don't get what it means to take 2 steps back to get ahead 1 step.
I'm so impressed with what Dr. Sanders surgically did for you.
Thinking of you...
