Patient discussion about ER

Q. I was in the ER because of a chest pain and the doctor there said its costochondritis. What does it mean? I am a 42 years old man. Last night i went to the ER because of a chest pain. The doctors there did many test and in the end they said its costochondritis. What does it mean? Can someone elaborate about the risk factors that can cause this symptom?

A. It seems that you are suffering from a traumatic injury to the skeleton that is near the heart which is called costochondritis. It can be a result of a simple trauma to the area or (as in my case, I am a rower) due to repetitive use of the muscles of the thorax and arms

Q. my husband is having trouble with him stomach or something. the e.r. doctor say's it's an infection in colan

A. hmm.. if it is an infection, then your doctor will surely give him antibiotics to cure that.
meanwhile don't be panic, if the symptoms don't go away, feel free to consult those with your doctor there.
