The Daily Breeze posed the following question about foot pain, which was answered by Dr. Barry A. Wertheimer, D.P.M.:

Q: Now that I am pregnant I have noted severe foot and other joint pains whenever I have to stand or walk for an extended period of time. What is the reason … and besides taking medications, can anything be done to help?

A: As many as 80 to 85 percent of women experience increased pain in their feet, legs, neck and back during pregnancy. Most doctors will tell you that wearing good shoes and massage is all that can be done to relieve the pain of this very common affliction. The reason for this pain is often the release of a hormone (relaxin) that allows stretching of ligaments in the pelvis to facilitate the birthing process. Since we live in a society that stands and walks on hard concrete surfaces, this hormone allows the feet to spread, flatten out and fatigue easily during the pregnancy. What is sometimes helpful is the purchase of over-the-counter orthotics, available at many sporting goods and drug stores. If not effective, then a custom-made foot orthotic, made by a podiatrist, is required to offer the greatest relief. Orthotics are custom-made supports that cradle the feet inside the shoes and hold them in a corrected position. They are a safe, effective, noninvasive treatment for the foot and posture. Orthotics also are effective in treating many other problems as well.
