After acupuncture, some blood comes out because the doctor who helped you with acupuncture touched the capillary when he injected the needle, which led to small blood stasis on the skin, which is what you said, and sometimes it is inevitable.
As for what you said, some doctors have little pain in acupuncture, while others are very painful. Acupuncture is very painful because doctors have insufficient clinical experience. Acupuncture pain is generally acceptable! Skilled doctors generally make guests feel no pain!
