Hi welcome to Health care magic forum.
Thanks for choosing H.C.M.Forum.
You had C.S.in september 2012. mirena
put in november 2012. Today when i touch on left side of your belly button, it is very tender.
The pain appears to be due to gastric pain, pancriatitis, renal colic
due to urinary tract infection
, or stones in the urinary system
. it may be intra abdominal hernia
I advise you to consult a surgeon, for diagnosis and treatment. You may need to have M.R.I. besides other routine tests for confirmation.
Wishing for a quick and complete recovery.
