Stiff on one side

[lizijj]

Hi, one of my youngsters is stiff on his right rein. Hill work particularly makes him sore and as he hasn't figured out how to stretch properly, is a bit of a numpty on the way home from hacks. Would appreciate any advice... already doing carrot stretches, raised poles...

Thanks

There is probably an underlying issue, if he is both stiff and sore , I would get a good physio, they will need vet approval, they will be able to get more to the root of the problem and treat if it is just muscular mine always checks the saddle which may be the cause of the problem.
Riding a horse that is sore will usually cause it to protect the areas that are sore and thus get worse, carrot stretches are useful for maintenance but will not resolve the problem.
If physio does not help I would be thinking of hocks and getting the vet but hopefully not in a young horse.
