Can a person have rigors without fever?
Patient: Can a person have rigors without fever? Twice now I have been woken in the middle of the night with violent, intense chills or rigors which lasted for over an hour involving my whole body. I am not sick nor do I have a fever. What could be causing this? Doctor: if you take my opinion then I would suggest you not to get worried and have all your investigations done for blood reports and blood count ,rigors can be psychological too, so don't get worried
