Hi welcome to Health care magic forum.
Thanks for choosing H.C.M.Forum.
You have been operated for
pancreas, and
kidney transplant, 15 years back. Yesterday you had sudden pain, and a lump, to the left of your bellybutton.
First thing is It must be confirmed, what it is, by having an M.R.I.then consult a surgeon for diagnosis and treatment.
As it is already 15 years passed it should be confirmed from where it is herniated. It may be herniation from other parts also, not related to previous operations .
Before consulting a surgeon, if you get it again, lie down on the back, and have smooth respiration, you may get it in. But it is not a remedy.
Wishing for a quick and complete recovery.
Best regards.
