Set-Fast or Tying-Up Syndrome will most likely be a permanent fixture of your horse’s life and can be very painful. In some instances, the horse is almost unable to move. Set-Fast/Tying-Up Syndrome is obvious when the horse’s limbs stiffen up during exercise and soon afterwards.
Set-Fast/Tying-Up Syndrome can be mild or harsh with symptoms varying from temporary cramp to serious muscle deterioration.

Diagnosis and Treatment of Equine Set Fast/Tying-Up Syndrome
A combination of treatments and procedures will be necessary to treat Set-Fast/Tying-Up Syndrome.  Ensure you call your veterinarian who will diagnose Set-Fast/Tying-Up Syndrome through blood testing to isolate any of the possible causes.   Some of the following forms of treatment will be recommended.   
For mild cases of the disease, in-hand walking may be recommended but for the more serious forms of Set Fast/Tying-Up Syndrome the recommendations may well be not to move the horse at all.  Pain killers such as Bute, correction of imbalances through fluids via IV, Corticosteroids and Muscle relaxants form the backbone of current Set-Fast/Tying-Up Syndrome treatment.
