BLUE FINGERNAIL BEDS? My son is 6, his nails are blue, lack of oxygen? Im concerned. Any ideas why?

He feels fine, earlier said he had a stomachache, but playing & fine. A little background, he has had asthma since 2, many daily meds, BUT in December all meds were taken away, crazy he has been fine ever since. More than fine. No episodes, attacks, healthy. laways in the back of my mind, will it come back. He has his bad month(October) so I am awaiting that. Dr. says take it day at a time, if it comes back, will treat again. Anyways

TODAYS PROBLEM: his nails are blue, i right away think hes not breathing well. I call Dr. immediately, the nurse is not concerned. She says with no other symptoms could be many htings, even a virus--(i never heard of a virus making blue fingernails) So nurse says monitor him, any other symptoms, they are there 7 days a week. SO what do you think? I am concerned, pediatric nurse not, 1 neighbor says looks strange, no blue lips, eyes, fine, no labored breathing. SO ANY SUGGESTIONS, THINGS TO LOOK FOR, CONCERNS, all appreciated!

alright, went to an urgent care, was going to send home, with close eye on him, but then called ER to check w/ them. Local ER said to have us come in for complete blood work up, toxology report, & oxygen report. So we went. from 8pm to 3am home by 4am. NOTHING! took blood tests, xrays of his heart. urgnt dr said maybe oxygen, maybe lead, carbon monoxide, many things--question was that blue nails & nothing else , no othr symptoms! all thought strange. hmmm. so here we are still with 1/4 to 1/2 of nail bed still blue. complained of stomach ache yesterday also at 6am this morning thought going to vomit, did not. He went to a great childrens hospital ER too! well any other info id appreciate, thanks to everyone!!!!

Are his lips blue? I know when I was a child I had blue fingernails and blue lips because of lack of oxygen due to a heart problem. It could be a number of things so I would get another doctors opinion!

Thanks for everyhting! Nearly a week later, all blue gone. LAsted for several days, 1/2 nail bed, to 1/4 nail bed, to just thumb & pinky blue, past 2 days, no blue at all. Still no answer to what caused it. Still a little concernned in the back of my head. SO ill be watching. Report It

It could be something else such as anemia. You should schedule a doctor appointment.

Blue fingernail beds is usually a sign of a lack of oxygen. I would absolutely get a second opinion. It doesn't sound emergent, but why wait??

go to the doctor right now screw the nurse...

BRING him to a doctor and have them look at his fingers - sounds odd to me. Bring him in right away.
