Hi, for last 5/6 months I've felt there is something not right. I've been to the Dr regarding feeling unusually tired (cat naps 6/7 afternoons) feeling/being sick. A full blood work was taken, every thing was lower end of normal I was given iron tables (I started taking Vit D,C and calcium) recently re tested but no change. I also have been having night sweats, being sick/nausea (no clear reason why) and difficulty swallowing (selivia,food) I've also found a small lump in my neck just under jaw (size of a peanut). We have Diabetes ( mum, cousin brother grandad) and leukemia (grandad, great uncle) in the family. Should I be worried?
