Can you post photos of him?
It's possible he may be suffering from injury or it may be Wry Neck which is a neurological Symptom - some common causes are trauma, disease and nutritional deficiencies.
You can try Vitamin therapy to see if he improves.
Go to your Walmart, CVS, etc. and buy a bottle of Vitamin E (400IU) and B-Complex. Give him 1 vitamin E pill and 1/4 tablet B-Complex daily for a couple of weeks. Offer him a treat of egg or tuna to help with the uptake of E.
What do you normally feed him.

I would
not use Goat Vitamin E and Selenium.
You would have to give 4ml to get 400IU Vitamin E and that would put you at 46.4mcg of Selnium which is way too high of a dose. Max Selenium dose is 25mcg for poultry, but it can be toxic in large quantities. Vitamin B1 is also a support vitamin for neurological issues and the goat vitamin does not contain that, so you would need to buy vitamins anyway.
