Does a change in the weather make people's joints ache?

Dear Cecil:

Often I hear of people complaining about their bones or joints hurting when they think the weather is going to change. Is there any truth to this? Can people really tell when the weather is going to change, or is this just some psychological phenomenon that has people feeling ghost pains when they hear a cold front is coming in? --Ann R., McAllen, Texas
