"started using gel for &quot;frozen toe&quot;. had pain about 75% of the time ranging up to 7 or 8. had difficulty putting on shoes due to bending of big toe. after using voltaren gel 2-3 times a day, after just 2 days pain was greatly reduced. and if there is any pain, it&#039;s only about a level 3 or 4.  have recently started using it on knees.  seems to help but not as dramatically as toe.  i really like that fact that very little of the diclofenac goes systemic."
