Interesting (but gross) story.
My son was complaining of a stomach ache. We took him to see Dr. Levey. He felt his stomach to see if anything was going on there and then, as always, checked for tickle bugs (my son is full of them :) ). Then after, my son was horsing around, he threw him, face down, over his knee and was bouncing him up and down as we talked (my son was bend over his knee w/his midsection over his leg). He stood him up and declared he was fine because if he had a tummy ache, the tickle and the bouncing would have produced screams, not laughter.
We had a med check a few weeks later and I mentioned that my son grinds his teeth. He looked at my son for a second and said "he had a stomach ache a few weeks back yes?" I said yes. He said "he has pin worms". HUH?????? How do you go from teeth grinding to pin worms? He asked my son "does your butt itch?" and my son said yes. He said that teeth grinding in kids can be the sign of an intestinal parasite. He said we can do two things. We can just give him the medication which is harmless to us but not to the worms or... we can get up at 3:00 a.m., take a piece of tape, basically wipe his tush with the tape and then send it to the lab for confirmation. Yeah, we took the meds. The interesting part is - he also gave us a homeopathic remedy for the teeth grinding as well.
He is a sole practitioner which means you may have a long wait in the waiting room but it's only because he just takes SOOOOO much time with his patients and their parents. Feel free to tell him the Foxx family sent you :)
