Soaking night sweats

I am 42 I've been having drenching night sweats nearly every night for about 6 months. I also have had a red throat and a small swollen lymph nodes in my neck. I have had my bloods done and my hormones are fine and my blood count is normal.  I am still worried, should I be asking my doctor to do a CT scan as I'm concerned it could possibly be lymphoma .
