I have begun feeling severe stabbing pains in my calf and the pain occurring in that region is starting to travel throughout my entire body, in which follows by deep coloured vains. As well as this I have been experiencing severe episodes of extreme sweating and dizziness which occurs on a daily basis. On top of that, both middle and index fingers are quite inflamed on the underneath tendons, and are continuing to enlarge. What do you suppose it is and how can it treat it at home.
