Hello Molly2121 and a warm welcome to Cancer Chat, 

It's reassuring that your GP bloods have come back normal but I can understand why you would want some answers as to what is causing these drenching night sweats. Perhaps it would be worth getting a second opinion on this just to make sure that it is nothing concerning and to see whether they would be willing to investigate further or give you an indication as to what may be causing these symptoms. 

I hope you will hear from other members who have had similar issues before and that they will be along shortly to share their experiences with you.

Fingers crossed that you get some clarity soon.

Best wishes, 

Lucie, Cancer Chat Moderator
