Fine-shouldered needles can be used, and the effect is quick, but the effect of fine-shouldered needles will not last long, and it can last for an average of 5 months. If the doctor who injects the thin shoulder needle is properly maintained and skilled, then the thin shoulder needle can guarantee the effect for 6 or 7 months. After the thin shoulder needle fails, it can be injected again, but not too much at a time, so as not to affect the recovery and health of muscles. I hope my suggestion is helpful to you.
