i frequently get small electric shocks and often see a blue line and here the shock too, why?

The phenomenon that you are talking about is caused by the same phenomenon that causes lighting, just a lot less harmful. When you shuffle your feet across the carpet you are causing a buildup of electric charge on yourself (it's also what causes your clothes to have static buildup) when you touch something that has a different charge on it, nature wants to equalize the charge. When charges move between points you have current flow. When you touch a good conductor, i.e. doorknob, the current flow is rapid enough to cause an arc(discharge).\nWhat you are seeing, hearing and feeling is the effect of the arc. The color is a preception becuase there is no preferential color to the discharge.

Sounds like WPW sydrome, or atrial fibrilation.  Go to a cardiologist and get an EKG.

Since this question is in the Engineering section, I assume you are talking about the corona phenomenon that occurs near high voltage power transmission lines and other equipment where high electric field magnitudes are present.\n\nCorona is common on high voltage lines and is caused by the high electric field strength surrounding the lines that locally ionizes the surrounding air. AC corona sounds like a buzzing noise and can be seen as a blue glow in the dark (more prevalent when the weather is foggy or rainy).  Corona also occurs at DC voltages, but has a few different properties.  See the link below for a more thorough explanation if desired.

if lots of wires, esp power cords, near spkr wire then may have hall pickup, or maybe bad neutral/ground somewhere\nunplug just the amp and see if still happens\nmaybe you just now noticed it - that is easily possible. you heard it once when your head was close and now you notice it always

I agree with all the comments. What I would say is whether its heart or epilepsy (brain), the situation needs attention now. I would suggest she goes to the doctor before it happens again. The doctor will likely identify the problem or refer her to an specialist. \n\nTESTS: An ECG would identify a heart condition and an EEG would identify epilepsy. Both these conditions can potentially kill, however, they are easily treated and controlled. Also, you can get blue lips as a result of epilepsy as well as heart.\n\nCHECK IT OUT NOW! Don't play with the heart or brain. Good luck. You are a great friend, she will listen to you.

Electric?  If you mean do you get shocked by everything you touch, then yes, that happens to me all the time.

please go to a doctor NOW ! there can be many causes a doctor will check blood pressure and heart. blood tests will show if you have to much or to little of anything. a doctor should be able to stabilize you. they may even do a brain scan to see if it is a electrical short or other going on.

You could be having an anxiety attack...are you stressed about something? Keep monitoring when it happens and then see your doctor. Good luck!

You should see a doctor - this could be anything from panic attacks to heart problems!

It's usually a sign of an infection.  See your doc.

If there's no immediate obvious explanation (like you just bumped it) - get a medical evaluation.  This could be an early sign of something serious.

It may be a sign of nerve damage.  See your doctor.

If it is really persistant go to a doctor but on the whole it is just an electrical feed back thing between nerves. I get it sometimes when I have been doing something like lots of computer work.

Go to a well qualified doctor.  My heart did that for years and was never cuaght on EKG.  Then one time I was able to get to the er when it was doing it.  I ended up having to get a cathader ablation done.  Were they go in your blood vessals with a fiber optic thing and zap some nerves in the heart.  it took two times but I have been fine ever since.

That has happened to me before also. It used to happen often and then I found out it was low blood pressure. Check with a doctor if you are really concerned about it.

This answer really depends on your age, sex and risk factors.  If you are young <35 its probably nothing serious but could be your thyroid, panic attack or rarely a heart problem.  If you are older, obese, smoke etc it could be a sign of something more serious in the heart and should be further evaluated by a doctor.  Bottom line if you have already been evaluated by a doctor and had a normal EKG its probably nothing but if you are still nervous you can ask for an event monitor.

not neccessarily, it really depends if your wearing shoes or not. of course your asking, how do i verify this?\n\nwell their is this thing called conductors and instulators. conductors means current can go through and insulators means it can't. the reason why humans get charged up because their friction causes electrons to build up in their body.\n\nso basically, touch someone else for fun and you might verify that shock.
