i have had knots, very painful knots a few times and im told its staph. i have one right now but its not as puffy and does not have squishy, soft spots. it seems like this hurts worse than before, which i didn t think possible. i have been told to watch for red streaks as it could be caused by blood infection and very dangerous. one side of this seems to streak, but i am not positive. i have read warning signs, and what to watch for and this does not seem to fit, but 1) should i go to the e.r. to be sure? and 2) if its not a blood infection, is it ok to wait a few more days and then lance it myself? i tend to hurt myself a lot less than the e.r. staff has in the past...thank you
