Whats the worst medical procedure you've ever had done. The worst i've had was having my nose packed, In February I had a nose bleed caused through high blood pressure, the bleeding wouldn't stop, so they proceeded to insert about a 2 inch long tampon into each nostril very slowly, the pain was excruciating.Unfortunately the extraction was even more horrendous, as the blood had dried on the packing. The bleeding then started again in earnest, which started clotting in my throat making me choke on the clots. Again they packed my nose, but this time one of them must have twisted, and started to poke the underside of my Eyeball for the next 36 hours. Oh the relief when they were taken out and I was allowed home.
