Had a hernia repair done the first of October in 2013. Since then surgery sight is sore and has a sharp shooting pain. First ct scan a month later showed a knot. They ruled out infection with blood work. Possible sernoma or scar tissue was suggested. Wait and see was response from Surgeon. It's now almost end of January and same pains but slightly worse at times. Recent ct of a couple days ago showed muscle separation and fluid in area??? Confused...please help.
