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...
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.
