Tubal ligation gone wrong?Is this malpractice? ?

I had my tubes Twice in 1995.i had an epidural for the first one and i jumped when the doc was inserting the needle and the needle went up my spine crooked.he had to do it over.while getting my surgery i didnt see my doctor just 2 interns.apparently they tied tissue on one side so i had to have surgery again but was knocked out.i was having major head pain and couldnt sit up so went to er and the nurse was yelling at me to stop being such a baby. the pressure was excrutuating.i had tears rolling down my cheek but i wasnt making any crying sounds.they put me on demoral and i still hurt because it didnt kick in yet.so they wanted to give me morphine.i said no but they had a shift change and the nurse put it through my iv.i was completly out of it.everything faded and went completly black.i felt like i was floating and was fighting my way back up.when i got home i was hearing everything in slow motion and i was so sacred from hearing people talk like one word was a minute long. i assume it was a drug overdose.
