Hands swell at night pain is so terrible last night i also had tightness in my chest today i'm tired could it be flu or a cold coming on ?

See you doctor: The symptoms sound worrying. Chest tightness and arm swelling may be unrelated however there is always a slight possibility of thromboembolism or clots in the deep veins and lungs. The simpler explanation may be that you are developing carpal tunnel syndrome in your hands. In any case you need to be seen by your doctors urgently to make sure there is nothing requiring urgent intervention

Uncertain: There are a lot of possibilities that can be in the realm of arthritis. You need to discuss with your physician. It is not characteristic of flu, but could be viral, bacteial,allergic or even systemic
