I saw your message last night, but was waiting to defer to someone with more expertise. However, I will say that I find the platelet count going up as a red flag. It can indicate a problem other than infection. (My own daughter has an elevated platelet count, that we are waiting to see a rheumatologist for).And the lumps multiplying? I wanted to ask if your doctor was a general pediatrician or a specialist. If a general MD, he may be groping for a logical answer, hoping it isn't more than an infection. If a specialist, then I bow to him.
