He may be dehydrated, gently pull up on the skin on the back of his neck and let go. If it does not snap back into place, he is probably dehydrated. Try to get him to drink, to eat foods containing water such as his rat blocks soaked in water to make mush, watermelon, baby food, organic soy infant formula - possibly thickened with baby cereal, mix up some baby cereal, ensure thickened with baby cereal, cooked & mashed sweet potato, etc
If he is unable to eat, you can give him rehydration fluid …. 1 drop at a time into the side of his mouth by syringe without a needle, so that it does not go down into his lungs
Homemade rehydrating formula: 10 oz warm water, 1 tsp sugar, 1/3 tsp salt. Mix well, refrigerate extra, warm up to feed.
Head tilt is a symptom of an inner ear infection.
Was he treated for this with antibiotics? For how long?
Has he seen a vet? Untreated inner ear infections will eventually kill.

Has he been eating ok up until today?
Has he been drinking up until today?
Has he been walking in circles? or rolling?
What is his breathing like? …. is it noisy? Laboured? is he propping his head up on hanging it down?
When you hold him up to your ear and listen to each side of his chest what does it sound like?
Can you post a video to youtube and then post the link on here?
Can you take him in to a good vet?
