So to shorten the story i have Chronic migraine so used to feeling crappy but past 6 months felt horrendous general fatigue bad achiness like after a gym workout flu like symptoms small lymph nodes ( for a year in armpits) Been diagnosed with Fibro and Undifferentiated tissue disease which may explain it but however recently ive also had night sweats even when sleeping naked . All blood tests normal / chest xray normal awaiting chest ct scan and lymph nodes apparently too small to biopsy with normal features on ultrasound . Im also doing a stool test . So far , nothing remarkable has shown - Is this unlikely to be. cancer and is there anything i should be considering . Im not depressed but feel so ill and sick of dragging myself about each day . Could fibro make me feel like this and are night sweats unusual in someone youngish who is definitley not menopausal or peri ? Thanks for reading !
