You state that your surgery was 8 months ago. I am not sure if
you had a laparoscopic surgery
or open surgery. If there was a
lot of inflammation at the time of surgery, it is possible to have
some scar tissue develop after the healing. You may have a
pinched nerve in that area under the rib cage
on the right side.
It is very unlikely to have an infection after all these months.
If you have post-operative complications, usually that occurs
within the first two weeks. Delayed complications such as a
retained stone in the bile duct can show up much later. This
is associated with fever,chills
, abdominal pain
and yellow jaundice
It does not look like you have any of these symptoms.
Just keep an eye on that area and you can apply some pian
relieving cream that you can find at a drug store. If the pain
gets worse, have your doctor check you for any additional tests.
I wish you well.
