Generally speaking, it is not recommended to go swimming after the injection. After the local injection will leave a needle wound on the skin, if the wound is not completely healed before swimming, it is likely to appear around the needle skin infection, allergies and other symptoms, and may even affect the effect of the injected drugs. In addition, the swimming pool is a public place, the water in the swimming pool is not very thoroughly sterilized, it is more likely to lead to infection at the injection lesion, or trigger the patient to appear to have skin disease problems. Therefore, in order to avoid secondary infection after swimming, it is recommended to swim after 72 hours of injection, and check the local injection site before swimming. If localized redness, swelling, pain and other symptoms occur after the injection, it is necessary to continue to postpone the swimming time.
