For years I've had this thing and drs are struggling to diagnose.
I come over all yuk feeling, when I get an attack I have a wave come over me, feel kind of shivery aches up the back of my neck, feel a bit nauseous. My insides creak and groan and I pass gas.
Sometimes (but not always) after it passes a bit I get cold and shivery - this morning I checked my temp and it was 34.4.
Often if I stand up and walk around gently it'll pass, but then if I try to relax eg sitting on my bed it'll come back.
I've been feeling yuk since Thursday and most of the time I'm lying on my side in bed, not feeling right.
I feel better standing but it's not practical to stand up all day! I just went for a drive and was mostly fine, even had a short walk and was fine, then got home and moved around, opening doors, going upstairs and it all came on again.
