Hi i hit a sign and fell off a bike about a half hour ago and have cramping in my calf and a stiff knee what can i do at home no other information leg was fine before

, : , obviously the cramp and the stiff knee is after the fall, if there is swelling , you should have an orthopedic surgeon evaluate , if there is blood in the joint space , it ought to be drained . Unfortunatelly , computers and human being need to be evaluated by an expert to decide on the proper solutions . On the other hand it may be only a transient post traumatic symptom and you may feel after seen the doctor , you wasted your time and money . But the appropiate thing to do is have the doctor evaluate why is stiff and why you have the cramping.
