After recovering from an infection, inflammation, or low platelet disease, a platelet count may occasionally climb very high for a brief period of time. Many children recover without experiencing any significant issues. A "reactive" increase of seven lakh may occur, and it may gradually recover to normal over time. The doctors probably believe your child is stable right now because they released him and told you not to worry. Maintain your child's hydration, take their medications exactly as directed, and show up for any recommended follow-up blood tests. However, get medical help right away if your child has a fever, unusual bruises, frequent nasal bleeding, weakness, breathing difficulties, swelling, or a severe headache.
