I've had constant pain for over two years (and had much sporadic pain before that). And I mean debilitating pain, not vague, dull aches. The only time I am not in pain is when I am in a certain position keeping absolutely still. Every time I get up from a chair or bed, stand still or start to walk, I am in pain. Anyone who tells you that pain is a state of mind, or something similarly glib, tell yourself that that person does not know what pain is. The important thing is to keep cheerful. Your body might hurt but your brain is still capable of things that are out of this world. We have one shot at life, so, pain or no pain, you get on with it with a smile on your face, trying your damnedest to not let people see your pain.
