Hi,
Has a chest xray been done to rule out any rib fracture, chest infection, or air in the pleural space?
There could be several causes of the symptoms you are having including a muscle pull, injury or trauma at the site, chest infection, etc.
Do you have any associated symptoms?
You should apply some local pain relief medications, take some oral pain relief medications, maintain a proper posture throughout the day, try some warm compresses.
You could take some antireflux antinausea medications and see if they help with your symptoms - this could be pain due to reflux or GERD.
Consult the doctor if the symptoms persist and discuss whether you need to get any investigations including a chest xray and ECG done.
Let us know about how you are doing and if you need any other information.
Regards.
You may have IBS (irritable bowel syndrome) which would explain the discomfort you feel in your abdominal region. And with IBS, the pain has a funny way of radiating to other areas of the body (particularly into the chest region, which is why many people confuse it with having a heart attack or lung problems). This is not to say that you shouldn't go back to the doctor and have some testing done to rule out other more serious possibilities, but IBS may be the cause of your discomfort and pain (even in your chest area). At least ask your doctor if it is a possiblility for you. Good luck!
