Typically, most clients find relief in 3 – 5 sessions. That said, the number of sessions is very much determined by:
What the problem is?
How acute (severe) the problem is?
How complex the problem is?
How long you have had the problem?
Will your lifestyle continue to contribute to the problem?
Have you multiple problems – if so how many?
The decision on the number of treatments is governed by results. If you are seeing real and measurable results and improvements we would recommend that you continue treatment. If you are seeing absolutely no positive results after the second session, I would seek to find other alternatives with you, rather than proceed with another session.
