Hi, my 9-year old son just had a Dexcom inserted yesterday. At first it was no problem but within a few hours he said it was hurting him quite a bit (5 out of 10, he usually says his shots are 1-2 out of 10). We gave him Ibuprofen before bedtime. This am he said it still hurt 5/10. I looked at it and the skin doesn't appear red or swollen. Has anyone else had this experience?
