Hi thanks for your question.
You had a fall one month back, not able to walk and above all swollen and tender area. All these features suggest the possibility of a fracture
, but can only be confirmed by x ray
. Go to ER or consult an orthopedic surgeon, who may order for an x ray of injured part to rule out or confirm fracture. Further management of your problems depends upon the report of x ray.
Hope this answers your question.
