I had been having some pain in my chest before. But Yesterday, I had this pain all day and last evening it hurt so much that I had trouble breathing. So I went to the hospital last night. As soon as I got there, the nurses checked my electrocardiogram. My blood pressure was normal. My electrocardiogram had arrhythmia but it was nothing to worry about. As a result of doctor's examination, I was diagnosed as "intercostal neuralgia". I got some medicines to ease this pain and see how it goes for awhile. The doctor told me if the pain continues, then I may have a fractured ribs. He told me to come to the hospital during daytime. He also told me that I was a bit skinny. If one's a bit skinny, one can get a fractured ribs without one noticing. For example, one can get a fractured ribs with just blowing a nose sometimes. He told me I better get some fat around my ribs. I felt bad because I never really had a doctor tell me to get fat! Anyways, until this pain goes away, I must stay quiet for a while.
