I've been having pain on my right side for about three months now, from right under my chest to right under my belly button. I kept running on it, and have only stopped a couple of times during daily runs. It concerns me more now because it's been hurting after I'm done running. Sometimes there will be a random spasm of pain in the area, and the other day it was hurting whenever I laughed. I've researched on it and tried a fix where you exhale whenever you land on your left foot, which helped a bit. I usually experience the worst during the second mile+ of a run. Any ideas on what it is or how to treat it?
