After ankle surgery ligamemts, cartiledge and plate I have bad calf cramps every morning, is that normalk? Clotting ruled out by ultrasound.

Electrolytes? Cramping can be part of the healing process, but if they are persisting for a long time, if may be worth visiting your surgeon and looking for other causes. If you are dehydrated, electrolyte imbalances can make the cramps worse.
Discuss with your. Surgeon. There are other causes of cramps other than a clot: vitamin deficiency is one. Possible side effect of medications, but I don;t know if you are taking any. Your doc would want to know of this symptom though so call them.
How long. How long ago was the surgery. Muscle spasm usually resolves within 3-4 weeks and can be improved with valium.
