Is a red line running up you L arm a sign a blood poisoning?

Answer 1

if the red line is following a vein up your arm comming from a cut, then yes it is possible! I had a similar thing happen to me when i was 8, i cut my hand on a metal spoke of a fence and had a red line going up my arm. my doc said it was an infection that went into my blood and scrubbed the crap out of my hand. I had to continue scubbing it for several days and mark with a marker where the red line was and keep my hand elevated. You should definitely see a doc soon

A similar thing happened to me...I noticed what looked like a Spider bite on my left arm, on the inside just opposite the elbow. I scratched it and picked at it because it was itching....it swelled up a bit. The next day I awoke to find a red line following my vein all the way up my arm to the arm pit. I went to the ER to find out it was blood poisoning, and was told that I would have been in BAD shape had I waited any longer. I was given a rather painful shot, and was released. It went away within a few days. DO go to the Doctor right away!

You have to take into account what else is going wrong with you. If you have a high fever, chills, severe pain, swelling, etc. (i.e. generally feel horrible), then it's likely a medical emergency, such as a bad case of lymphangitis.

If you are walking around painless, with no fever, its likely due to an ascending infection from your foot. Take a look at your foot, you might see some cut that might have gotten infected.

Regardless, call your doctor to get it checked out.
