Your nails have to have oxygen because the under lying part is still alive.  The top is dead cells.  Without the oxygen it can get fungus or infections.

are you wearing a ring that is cutting off your circulation?  That would be my first guess.

This can also be a zinc deficiency. No matter what kind of deficency it is, just take a good multivitamin.\n\n Make sure that you take a good multivitamin, and in a few weeks check the tops of your nails again, as it takes a few weeks for the nails to grow out.\n\nIf you're still having problems after a few weeks/months with your nails go to your doctor about it, and he can help you with it. \n\nBut it's probably just a nutritional thing.

Does your heart beat funny for a second or two?  If so, I get that.  It's related to anxiety and stress.  I also got it a lot when I smoked or drank caffeine.  Call your doc and make sure it's nothing serious though.

I can hear mine sometimes also. As you say, it happens ina quiet place. As the other answer say, ask a doctor. But guess is something normal but not everyone has it.   Be yourself and take care of the thumps ald fill it with love. Take care.

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

Since I'm not the one squeezing them, I can't tell you. You need to get an appointment as QUICKLY as possible. This can be very serious. It might be nothing, but you better be safe than sorry.

you probably had a type of palpitation called a PVC or PAC- your heart just beats a little too fast and gets ahead of itself. lots of people get them, theyre harmless unless you have an underlying problem like a heart defect. if you just get one here and then that's pretty common and youre fine. if youre getting quite a few, youre still probably fine but should get it checked out just to be on the safe side. \n\ni have them bad, i literally get thousands some days, it sucks. they still scare me some even though im pretty use to them by now...

It's probably more annoying than life-threatening.  Sometimes a compressed vertrebral disk or spinal nerve can do this.  You have not described cardiac involvement.  Please don't ask for an online diagnosis and ignore any that you are given.  I suggest you see your health care provider for evaluation.

Ummmm, because you ate licorce ice cream? You put black lipstick on them? They got frostbite (call your doc STAT)?  You have poor circulation in them and they have become necrosed (dead tissue.. in this case, call your doc STAT... you have some serious problems)? Your are not breathing well and your oxygen levels are low (here again, you need medical attention STAT)? You have African DNA in you?\n\nDoes any of the above help?

Guessing here, but our toenails are thicker than our fingernails, so that could have something to do with it.

Sounds like Raynaud's Syndrome.  My mom and I both have this.  I've heard that there are some meds you could be given, but you're really best to just do your best to keep warm.  It's not usually harmful, but do talk with your doctor about it, as it can be a symptom of other circulatory problems.

It feels like a mild pinch by someone with long fingernails . . .not too much pain at all . .\n\nmy advice . . .if you're squeamish, don't look at the needle, and don't watch the blood coming out . . .just turn your head or shut your eyes, and keep them shut for a minute or two.
