Name that Pain

My back hurts. Also my right foot has a pain in it. I have felt shooting pains in both breasts. I am certain that I have had random pains in my life before and not worried that it was cancer. I just don't remember what that felt like. It is a constant battle to tell myself that these are normal aches and pains that people get from overdoing it, or straining a muscle or being tired. I have a very good imagination and unfortunately every time I have an ache or a pain of any kind, my first thought is that it is cancer. When do I get to go back to not worrying about all of these things? When do I get to accept the fact that it might just be something as simple as a pulled muscle?

I keep remembering that great scene from Kindergarten Cop with Arnold Schwartzenegger when he has a headache and the kid tells him "it's probably a tumor". Arnold's response---"it's not a tumor!"

I will try to put Arnold's voice in my head every day and every time I feel an ache or a pain. "It's not a tumor!" If Arnold says it, it must be true.
