I suggest you ask your doctor investigate acid reflux and gal bladder issues.
Another option would be a dislocated, bruised or broken rib. Did something happen six weeks ago that could have cause something like that? A fall or any otherr kind of accident? Severe coughing?
Just some thoughts. Feel better.
If your doctor said you have pleurisy, that is inflammation of the lining of the lungs and chest. It is often a sign of a viral infection of the lungs. With anti inflamatory meds and REST might help... I felt the same way only that i had the fluid around my heart and it needed to be drained.
I wish you well, but i would follow up with the doctor, possibly a lung and heart doctor. if it does not get better within 5 days of starting the anti infalamtory meds. I found that REST was very important.
Feel better...
