I have not had that problem (9 years after my donation). I have read of several donors who had incisional hernias and had them repaired, but within a fairly short time after the surgery. I suggest that you contact the hospital where your donation surgery was done. They are supposed to fix, for free, medical problems that are results of the donation but I don't know if they would do so years after the donation. I am not a medical professional, but I wonder if there was a small incisional hernia shortly after the donation and that it has just recently gotten worse? In any case, contact that hospital forst.
Please let us know what happends.
