There is no guarantee this is a virus. There are plenty of other things that cause illness like this....
pnuemonia
bowel obstruction (greenish vomit)
ear infections
giardia
septicemia
thyrotoxicosis
meningitis
urinary tract infection
Kidney infection
mass bacterial infection (shigella, campylobacter, strep, etc)
pancrease deficiency
severe loss of electrolytes or body water (Shock)
11 years ago I took my 2 yr old into the doctor because she wouldnt eat, and had a high fever of 103. I was sent home on four different occasions with tylenol and told it was a virus. She was getting more sleepy as the days went on,barely staying awake (only after tylenol could she stay awake for about 1-2 hours) then vomiting on her pillow at night. At about day 8, my daughter was starting to go into shock. Her eyes were sunken in, dark circles under them, her lips were turning pale and blue, she could not stay awake, and she started to halucinate- she told me she was seeing monsters in her room.They finally did a urinalysis and found the infection, a massive amount of bacteria in her urine from her kidneys. It took 2 more days for the antibiotic to start working. That 10 days of infection changed my daughter's life forever.
The high level of multiplying bacteria in her body and kidneys caused bleeding into her tissues around the infection site -( the adrenal glands) which sit on top the kidney. The adrenal glands put out hormones and control every aspect of your body functions from the way your heart pumps to your kidney function and blood sugar regulation. That infection damaged them, and now she doesnt put out enuogh hormones to keep her body going. She has been sick with arthritis since 3 yrs old. now at 13 she gets dizzy, faints, blacks out, gets chiils, and goes into blood sugar shock, and I fear one day she could even die, she gets SO Sick on a daily basis. She just got diagnosed and her condition is called Addisons if you want to look it up- and it is DIRECTLY caused by failure to promptly treat a bacterial infection. (TB, meningitis, kidney infection or shock)
Everyday I cry, and WISH that i had gone with my gut and taken her to the hospital during one of those evenings while i sat worrying about her and wondering what was wrong. I implore you, do not wait anymore. Get her to the hospital -NOT a flunky pediatrician. 8 days- he has got to be kidding. where did he get his degree from, a cracker jack box? Go to the hosplital in the evening if you have to, when the doc office is closed. The emergency department WILL do the blood tests that the doctor will not do.
The human body was NOT designed to go 8 days with throwing up. I have never gone that long with any virus- and i am 46 years old so i have contracted a lot of viruses in my time. Really,only a 24 hour flu kicks my rear. 8 days is drastic- I think her condition is much more serious than your pedi is considering. And even in the chance it is a virus, your daughter is in grave danger from being severly dehydrated and going into shock. The biggest thing you should look for is listlessness- a real danger sign.
Google metabolic shock and hypovolemic shock. Both of these situations can lead to permanent health damage. Get her in now. Don't walk out the door without testing done. The first thing they should do is get her on an IV to get her body fluids back up. No matter what.
the second thing they should do is run a complete blood count and probably stool tests.
Her electrolytes should be tested, probably via saliva. Vomiting will upset the body's delicate electrolyte balance (potassium and sodium levels) leading to high sodium and low potassium. low potassium affects the heart beat, causes high blood pressure, a decrease in urine/weak stream, general weakness, and paralysis.
I want to say something about medicines. The tylenol the sent me home with to give my DD every 4 hours- it covered up how sick she really was. She would get better for a few hours after, almost back to normal.Subconsciously i think it made me feel like she was not as sick as she was. That is what any anti nausea drug they give you is doing. it's covering up her bodys only way to show you how sick it is. To this day, i do not ever give tylenol to reduce a fever.
I am praying for her health,
Good luck mama and God bless, Gail
