Stuck needle is a common problem in scalp acupuncture.The doctor may experience a sticking feeling when twirling，lifting，thrusting or withdrawing the needle，meanwhile the patient feels pain.
Prolong the duration of needle retention when a needle is stuck.Ask the patient to relax and use gentle massage around the needle.
Stuck needle is often caused by rapid unidirectional twirling of a needle.Special attention should be paid to manipulation techniques.Manipulate the needle with even force and avoid unidirectional twirling.
The needle body（shaft）bends or breaks inside or outside the tissue.
Stop lifting-thrusting or twirling when a needle is bent or broken.If needle body has slight bend，withdraw it gently.If the bend angle is over curved，withdraw it following the bending direction.Don't withdraw or rotate the needle forcefully to avoid breaking the needle in the patient's body.If the needle is broken，and its broken part protrudes from the skin，remove it with forceps.If the broken part is close to surface beneath the skin，compress the skin with fingers around the needle to expose the shaft，and then remove it with forceps.If the broken part is completely embedded under the skin，surgical removal is required under the X-ray.
To prevent bending or breaking needles，it is necessary to check all needles carefully before using.Never use any rusted or bent needles.Also the patient should be told not to disturb the needle to prevent bends or breaks.
Blood vessels are rich in scalp，tissues and needling may cause local pain when a inserting needles into scalp tissue or during needle retention.The needle hole may bleed after withdrawing the needle causing local swelling and pain.
The micro subcutaneous hemorrhage does not need special care.I twill disappear itself.If local swelling and pain is severe，alternatively apply cold and warm compresses to stop bleeding.Mild massage promotes the absorption of blood stasis and decrease the swelling.
Before acupuncture treatment，examine needles carefully.Be familiar with the anatomy of head，and avoid puncturing the blood vessels.Press the needle hole with dry disinfected cotton balls after withdrawing the needle.Reduce the time for needle retention，withdraw the needle gently and fast in those who bleed easily，and press the needle hole immediately if bleeding.
