Hi I have had a swollen lump in my left wrist vein for about 4-5 days. Sometimes it throbs with a bit of pain. I have been working at computer long hours today, with breaks, and when I quit to night I got up and was feeling dizzy, the throbbing started in my wrist again, I drank a couple glasses of water. I am not having any sharp pains, but am feeling dizzy, anxious, and shaky. I almost felt like I was going to pass out. I am not getting worse, but still a bit shaky. I was feeling kind of weak, but I may be stabilizing now. I had not injured my wrist, and it is new that I can see a slight bluish coloring swelled spot on my vein, below the left thumb. I don t know whether me thinking it could be like an aneurism is getting me anxious or maybe I got dehydrated today...I don t know. I normally have a bit lower blood pressure. My breathing is good.
