After being hit with a hematoma and bruise, a local cold compress can be applied, which can play a role in constricting blood vessels and reducing the blood flow rate to reduce the local tissue fluid exudation and prevent further aggravation of the hematoma. At the same time, it can also reduce nerve sensitivity and play an analgesic role. Intermittent and repeated cold compresses can be applied, but avoid too long to prevent frostbite. If the situation allows, the affected limb can be elevated as much as possible to reduce the blood flow to the area to avoid further aggravation of the swelling. 48 hours later, a local hot compress can be applied. This can dilate blood vessels, accelerate blood flow, increase local blood circulation, accelerate the metabolism of hematoma and bruising, and reduce local tissue congestion. It can reduce nociceptive nerve excitation, reduce peripheral nerve compression and stimulation, and thus can relieve pain. In addition, you can also use drugs for treatment. Topical drugs mainly include safflower oil and bruise medicine wine. You can also take Panax notoginseng tablets and Shujianliu capsules orally. If the local pain is strong, non-steroidal anti-inflammatory and analgesic drugs, such as ibuprofen, can also be used. If the hematoma is large, it needs to be incised and drained to drain the contents, and then anti-infective drugs, such as penicillin and metronidazole, are used. Less symptomatic hematomas and bruises are self-limiting and most people usually recover largely in about 1 week. If symptoms are not relieved, it is recommended to go to the hospital for timely treatment, including Chinese physical therapy such as infrared and light wave physical therapy.
