Aches & Pains

Do you ever have aches & pains & think you have some life threatening illness or terrible disease? I am not a paranoid person but must admit that occasionaly I have an ache or pain & think "what if". What if this is the one, the grand daddy illness that will end it all or knock me into another place? I don't know if it is just me or if all of you do the same thing but one thing I know, is that just thinking about what hurts can be stressful, if you think about it to much. I know that drugs & stuff isn't the answer & that we need to deal with life, not run away from it but, occasionaly a thought slips in for a moment & makes me wonder?
