First, newer injuries, if treated appropriately and immediately, tend to respond to fewer visits assuming that major tissue injury has not occurred. Many of these first time injuries can be effectively managed in as little as 3 to 4 visits. Conditions that have been present for greater than 3 months and recurring conditions are generally more stubborn and difficult to manage. Resolution may require 12 visits or more.
The only sure way to determine how long your treatment will take is to schedule a consultation and/or examination.
For those of you who believe in just waiting for the problem to "go away" on it's own - understand that the longer your condition has been around, the more treatments it will eventually require to resolve.
