Caroline, that is so funny you say that. I did just switch his Smartpak to Smartflex IV and it will be coming in March. And, my next course of treatment (which hopefully I don’t have to try) would be shockwave therapy. We are about 15 min from WI Equine Clinic and Hospital who has an excellent lameness specialist so that would be our next stop if needed. I haven’t really ridden so can’t tell too much if the injections have been helpful. On vacation next week and then when I return on the 7th I will start on him again to see how he feels. Thanks for the suggestions!
