How does acupuncture relieve pain?

When you put needles in certain places in the body, you will relieve the pressure oftentimes on a nerve such as a cranial nerve that affects the head. By relieving that pressure on a nerve, the muscles begin to relax, the blood begins to flow into an area, and pain is released partially through that mechanism and partially through the nervous system releasing endorphins and encephalins.

How many treatments will I need to cure my pain?

The number of treatments required depends on the severity and duration of the 
symptoms to be addressed. For a acute pain, one or two treatments can be very 
helpful and the effectiveness of the treatment is often evident.. For chronic conditions 
of years or even life-long duration, a longer course of treatment is normally required. 

what are the risks of acupuncture?

Acupuncture is a relatively safe treatment with minimal risks if done by a trained 

practitioner. But depending on different treatment on different locations of your 

body you may see minor bleeding, bruising or local skin rashes. Those are very normal.
