Just seeing this! Poor little Marcel! This is horrible, Ann! I'm so sorry your sweet baby is going through such a bad time. I know you're sick with worry and I'm praying for him.
Have your heard about the little girl who recently who suffered temporary paralysis - this little girl couldn't even stand - from an unknown tick bite? Have you checked every inch of him for ticks or evidence of a tick bite? If tick venom could paralyze a child, could an unfound bite cause neurological problems with little Marcel maybe?
