I posted this reply a minute ago:
It sounds like what you are describing it a condition where the platelets are low called idiopathic thrombocytopenia purpura (ITP) where the child has easy bruising and bleeding. If the platelet count was 17,000 then that can be quite serious with even spontaneous bleeding in organs, including the brain. It is treated with either steroids or more commonly with IV immune globulin when severe and that is determined by the hematologist usually.
As to travel, I would not advise this with his platelets that low, if indeed they are at 17,000 right now.
I'll watch for your reply as it seems you might not be at your computer.
I see another doctor has decided to insert himself into our conversation. I did see your last question and have to tell you that he needs to be evaluated by the hematologist as this can be quite serious and I've see children have major bleeding and even die with this.
Thank you for your expertise. sorry I might have sent many e-mails. Trying to get use to computer that was just bought. we are going to take him into the City, to be seen by a Hematologist. I appreciate your evaluation. I well keep your assessment in his file, and will consult with you if necessary. Thank you again.
