"i fell and injured my knees.  i have had pain for three weeks.  with one application of this medication i was pain free.  of course i am in the process of x-rays and an mri if needed.  i really like this drug.  i only wish my insurance would cover it on the lower end.  i cannot afford to keep using it at the price it is now.  it is not very expensive but i am on a limited budget.  i give this medication a 10 if not more."
