I have redness of the eye ball and lid, burning and feels like gravel under tbe eyelid, is this pinkeye?

Check for Grave’s disease. I had a gritty, sand-like sensation in my left eye. Doctor picked up
on the Grave’s disease problem, which is thyroid related.

yes, it may be pink eye. see below link:
