Mirena coil

I had a biopsy done at weekend on a cyst near my cervix(no probs) was also having coil fitted, I was in so much pain after 4 attempts it was decided I'd have to go in as a day patient,I'd taken paracetamol as told plus I'm on strong medication(morphine slow release tablets 60mg plus notriptalene at night) god knows how bad I'd have been if didn't take meds I do, I felt sick afterwards also
