Pain that runs along the course of a rib is a common complaint, especially during pregnancy. The patient will often come in complaining of a shooting pain that can also be felt as a burning sensation, and more rarely as an itching sensation. The pain is usually worse with activity and can be become very acute with coughing, sneezing, laughing, bending over, rolling over in bed and other movements.
Rib pain that affects the nerve as described above is a form of Radicular Neuralgia, a condition where a nerve is irritated and can cause pain and other symptoms along its course, including pain, burning, muscle spasms and/or itching. Intercostal Neuralgia is the name for this specific type of radicular neuralgia. Intercostal neuralgia is most likely by an irritation to the nerve where it exits the spine at the joint between the spine and the rib, also called the Costovertebral joint.
Pregnant women are more susceptible to this complaint due to the postural, hormonal and weight changes of pregnancy. The hormone Relaxin causes ligaments to become looser and makes women, with the other normal physical changes happening, to be more at risk for physical complaints from injuries and activities that might have normally not been a problem. 
Chiropractic care, from a doctor that is trained and experienced in working with pregnant women, and who has specialized equipment to accommodate a pregnant patient, can be extremely helpful with Intercostal Neuralgia and Radicular Neuralgia.
