My horse has this in his hind right leg. It causes his leg to swell up and "tighten" up. He can not move as "flowly" as i'd like. He does not really head bob but he has more of a hitchy step on this leg. He has his good and bad days...Has anyone else delt with this before? Is there anything I can do to KEEP it down or even get it away? Please let me know! I wrap it when it is puffy and put linement on it, he gets a shot of ECP 1x a month and is on cosequin joint supplement. Thanks guys!
