Sorry to hear that Ross,,
I remember all too well the feeling I had when I pulled one off my 3 year old...just a few years ago. Absolutely sick to my stomach, kept it in jar in case they needed to test it. When he was cleared, I slowly tortured that bastard for a few days.....didn't make me feel any better,
....but since then, I do my best in giving him a full body inspection.
Such a difficult creature to protect yourself from. Even in clothing, you can actually bring them in the house.
God - Speed for a full recovery my friend.
