Also, last night in his speech he described how the doctor said the ear bleeds a lot. None on his hand. None on the white cuff of his sleeve. Even as he drops to the ground after covering his ear, his hand is momentarily visible... no blood.
I am not positing a theory. I am asking about what looks like an inconsistency.
We could see the blood run down his face. He may not have cupped his ear tightly enough to get blood on it. He didn't know how much damage was there, and may not have wanted to do more. I think it likely he didn't know for sure it was just the ear.
His ear drum was probably giving him problems as well. Noticed that Trump was the one telling the others to duck, not the other way around.
