There are 2 factors that affect the speed of your recovery.  These are Duration and Level of Severity.  For example, if your injury or discomfort is fairly new or acute—meaning that it occurred 3-4 months ago, the results are faster and will most likely take 1-2 sessions.  If the Level of Severity is mild to moderate this will also speed the recovery. 
With more chronic or long-standing cases, again, this varies according to your specific condition.  However, anything that has accumulated over time and became worse over time requires more frequent sessions. 
Here is another way to look at it.  You can’t lose 50 lbs in one day and this holds true as well with Medical Qigong Therapy.  If it took years of accumulation it will require more sessions and lifestyle changes.
