My Left Ear Has Started To Hurt After Smoking Weed.

My left ear has started to hurt after smoking weed. It feels like a little bug or a lot of pressure is being put on it. I know there's no bug cause I clean my ears and this isn't the first time it's happend. It sort of feels like it's really heavy. I smoke weed very day and only get this pain randomly. I have thought it might be my tooth that's causing it to feel like this because that is aching at. Random times too. I don't know. Is it linked to my Toothache, weed or is it something more like an infection?
Thanks
