question: The past week or so I have been having pain in my chest. I had a doctors appointment today so I asked the doctor about it. he told me that I have costochondritis and he gave me some pain meds to take the for next 3 or 4 days. I have also been putting heat on it. I am preparing for a half marathon in a couple weeks so I run a lot. I didn t think to ask if it s okay for me to run or if I need to wait until it stops hurting. Will it be ok if I run or should I wait?
