my horses neck looks swollen

Question

horse on right   My horse has been at another part of the  farm for sometime now and my husband brought him home yesterday. I noticed today that his neck looked swollen at the crest. It may be totally normal idk but I don't remember  his neck ever looking like this. Any info would be greatly appreciated thanks

Answer
Ashley,
A couple of things come to mind. You didn't give much detail so let me ask some questions. Was the horse on good pasture? Is he overweight?  What's his age? If he's approaching or in his early teens consider possible Cushing,
's syndrome. That can make horses cresty. Just being overweight can too. If he's not overweight then palpate the area and ask him to flex his neck. If after all this and you don't find anything and he's not fat then you may want to get him checked by the vet. Not seeing what you are talking about makes it hard to figure out much.

I wish I could be more helpful but I don't know enough to do more than make some suggestions.  

Sorry.
