After eating the top of my mouth had a tingling sensation is this weird?

Pesticides/allergies. I think unusual is more apt than weird. This may be a symptom of food sensitivity or could be due to pesticide exposure from residues on the food. For example, grapes that aren't organic can have enough pesticides to cause this- see http://tinyurl.com/jaz3xpw for other common culprits. I used to get tingling/itching from apple skins. Other foods could also cause. Pay attention to what foods cause.
