Hi. Does anyone have experience with front leg lameness that is caused by problems in back or shoulder or neck og some place else than the lame leg? Horse is lame and vets can't figure out why. She is lame on a circle on hard ground. Sound on a circle on soft ground and sound on a straight line on both hard and soft ground. Lame when ridden on left rein, sound when ridden on right rein. Feels like she sometimes is lame going downhill. Lame on both legs sometimes, but more lame on the left than right. Have now startet thinking shoulder, back or neck. But what can it be?
