If there is swelling and pain, it is necessary to determine the specific cause and identify specific medications to be selected to reduce the swelling and pain. If the swelling and pain are caused by infection, such as localized abscess formation, standard anti-infective therapy is required, either penicillin or cephalosporin antibiotic infusions may be chosen. In patients with severe abscesses, incision and drainage should be considered. Painful symptoms will be effectively relieved by controlling the inflammation. If the swelling and pain are caused by traumatic factors, cold compresses can be applied within 24-48 hours after the injury. Cold packs or ice packs can be used to reduce the release of inflammatory mediators and vascular permeability to control the symptoms of swelling and pain. At a later stage, the affected limb can be elevated, local hot compresses can be applied, Yunnan Baiyao can be sprayed or drugs that promote blood circulation such as Panax notoginseng tablets can be taken orally to improve local blood supply.
