i went for a heart by pass and had an anaflexic shock to the anesthetic, they had to fight to bring me back the surgeon said he thought theyd lost me, i think that the nhs should test people to see if they have allergies to medication used in surgerys like this. i dont want to sue the hospital or doctors nurses as they were fantastic, i couldnt ask for better treatment and care, its the fact that nhs dont test for this problem, im now suffering depression, anxiety and flashbacks to what happend and rarely go out of the house anymore,
