I've got this thing with my right carotid artery it's way bigger than the left one, like three or four times the size, and the other side's totally normal. When they first found it, one tech thought I needed emergency surgery, but then another doctor said it wasn't a big deal. Im 37, pretty healthy, and there's no family history of vascular issues. The only thing that bothers me is this ache I get when I'm exercising. Just wondering, is there something I should be worried about down the road?

Thats unusual and needs evaluation visit vascular surgeon for proper evaluation and appropriate management
