Anybody have a pic of what a warble looks like on the cow??

We have a 2 year old bull that had a knot just develop on his back. Thought maybe he hit it but there is another one about 6" back. We just wormed him with Cydectin about 2 weeks ago. He is a gelbvieh/angus cross, big and fat probably close to 18-1900lbs. So then someone suggested warble. I don't see a hole and he is WAAAAY to big to catch in our headgate to check it out. So.....any suggestions??? Thanks!

No pic, but a warble would be about the size of the 1st joint of your thumb, maybe a little bigger...
