I don't know if this is the right place to post this question. Can anyone tell me which local anaesthetic is the best one for people with ME. I've heard that those with adrenaline are particulary to be avoided. I am getting prepared to have my mercury fillings out, my dentist uses Octapresin (Cytanest), but I already inject a few times a week magnesium with .5ml lidocaine and am okay with that. I asked the receptionist if he uses this but she said he didn't. I am prepared to ask him to use a specific one if necessary, I have a lot of treatment to have and don't want to jeopardize my chances.
