My husband had 2 inguinal hernias and one higher up on the left side of his stomach repaired via skin incisions on March 1. He has been able to eat and had a little trouble urinating, which has gone away. Dr had him on hydrocodone and today my husband decided he wasnt in enough pain for that and took Advil , 3x since 5am this morn, at 7pm, he said there was some blood in his urine. He has no other problems, is it the Advil, causing some internal bleeding?
