Hello, I have been on a waiting list for a l5s1 discectomy, which will be performed next tuesday under a general anaesthetic. i have developed a slight cold over the last day, sneezing, and mypartner has a heavier cold. Should I tell the hospital? I don't want to have the operation cancelled as I have been off work for so long, I want to get it over with. Will the anaesthetist be able to tell anyway? Is there any danger in me not telling them? I am otherwise a healthy 40 year old man. I do have hydrocephalus controlled by VP shunt, but there have been no problems with this for the last 13 years.
