My wife and I left went to London for a vacation. When we returned my 3 year old lab was acting very strange. I could tell he was in pain but couldnt put my finger on where. Then the next day he was fine so we did some a 10 minute training session for fun and he seemed perfectly fine. Then he was fine a whole week. Then yesterday I noticed he was in pain again so I took him to the vet. When the vet was looking him over he showed pain when turning his head left. Also, we noticed he will not look left. He gave me some previcox and tramadol for pain and inflammation he thinks its muscular. I spoke to a friend who is a vet and he said it is common and he calls it a pinched nerve. I'm baffled I don't know how it happened. I do know when we got home he seemed fine for the first minute then I think the excitement with the other dogs and them rough housing is when it happened. Im hoping he heals and he doesnt have to live like this for the rest of his life. Any thoughts?
