Hi, I was in a car accident 4 months ago and bruised my ribs. The xray performed by the ER showed no broken ribs or punctured lung. So the doctor said they are probably bruised. After 4 months, I still feel a noticeable discomfort whenever I jog, lay on my side to sleep, run, etc. Is this normal for bruised ribs? Is there any steps I can take to lessen the discomfort or heal the ribs? Thank you
