Bruise: If only in 1spot and perfectly, may be a bruise or pinch mark may take a week or so.

Question 2

if you have petechia rash does it it spread quickly?

Accepted Answer

Variable: A petechial rash (caused by low platelets) can appear on any part of the body. It can stay localized, or appear on other parts of the body. It does not really "spread" like a rash caused by an infectious agent.

Question 3

doc confirmed localized petechia rash on shoulder, said no worry as there was a history of minor trauma as i had hit it. said blood tests not needed?

Accepted Answer

Trauma no blood test: If there is history of trauma it can cause petechae and you do not need blood test
the most common cause of petchae is physical trauma and it will clear up by itself.In a case like yours it is up to the examining doctor to decide if you need blood test for platlet count.Some doctors will order it just to be on the safe side.Some will only do it if there is recurrence of petechae.

Question 4

my 10 year old daughter has slightly increased prothrombin time.  also has a possible petechia rash.  liver and platelets are normal.  any ideas why?

Accepted Answer

Need evaluation: What is the actual prothrombin tine and what is her inr? If she does not have symptoms, it may be better to wait and watch. If she has more than "possible" petechiae, please see your pediatrician as it may need more history, physical examination and lab tests.

Question 5

Accepted Answer

Who knows? : Hard to say with such limited history. If you have petechia like rash please get an appointment as soon as possible, it needs to have prompt medical attention and evaluation!

Question 6

earlier i was crying and started itching my skin,now i noticed petechia on my breast/shoulder,is that odd? does that happen?how long does it last?

Accepted Answer

Common: It is not unusual to develop petechia as a result of scratching the skin - the duration of the petechia depends on how vigorously you scratch.  It can last a few minutes, a few hours, or a few days.

Question 7

i had an influenza- like illness last week (tested negative). now i have petechia on both legs from my ankles to hips, i otherwise feel good now. ?

Accepted Answer

See doctor: Petechia can be a sign of inflammation of the blood vessels, called vasculitis. Even though you feel better, I suggest you have your doctor take a look, and probably do some simple blood tests to look for signs of inflammation and check your platelet count (platelets help in blood clotting).  Call today. May be nothing, but it's best to get checked.

Question 8

i have petechia on my skin but i haven't scratched that area. should i be worried?

Accepted Answer

Petechia: if u  have easy bruising or bleeding  get a cbc to check your platlets

Question 9

is petechia a sign of hiv?

Accepted Answer

HIV: Petichiae occur due to either capillary fragility or to some defect in coagulation, usually platelet deficiency.  The latter may occur due to a wide number of mechanisms, many of which can be seen in either acute HIV disease (splenic enlargement or bone marrow disease), or due to any of the infections or malignancies that following profound immune deficiency due to hiv/aids.

Question 10

Accepted Answer

Drug,infection: This could be from medication or an infection, but there also could be something wrong with your platelets.
