Symptoms of costochondritis: Acute pain very similar to that which occurs during a heart attack. It gets worse after trying, deep breathing or sneezing. Decrease with slow breaths and rest. The pain radiates to the back of the neck and shoulders. It appears and disappears according to the day. It affects the section of ribs located between the 2nd and 5th. Difficulty moving the upper part of the body. Rapid heart rate Irregular heart rhythm. Difficulty breathing. The relationship between the two diseases is not known, but fibromyalgia is prone to suffer from costochondritis, which is exacerbated by other fibromyalgia pains.
