It's right there in the name: in dry needling, needles are inserted into muscle knots, ligaments and tendons - think any points of tension. The goal is releasing stiffness.
If you've got a stubborn sports injury, or some muscle stiffness that just will not leave you alone, dry needling could be what you need.
Acupuncture intends to treat the chi or qi energy for a patient, and needles are placed along energy meridians according to Chinese medicine practices. Dry needling practitioners place needles around areas of tension to treat physical areas of pain or discomfort for a patient.
This varies, but you can expect to go once or twice a week initially, and then to drop down to once a month.
You might be a little sore in the treatment area, and some people do experience bruising. Make sure to drink plenty of water, and rest if you feel you need it. Stretching can also be great, but of course, stop if you feel any pain.
