Swelling of the arm by squeezing can usually be relieved by general treatment, physical therapy and medication. 1. General treatment: the affected arm can be elevated above the heart level, which can promote venous return and eliminate swelling. Within 72 hours after being squeezed, ice packs can be taken, and after 72 hours, it can be changed to hot packs. 2. Physiotherapy: It can be combined with microwave, baking lamp and other physical therapy to help promote local blood circulation. 3. Medication: If there is obvious pain or serious swelling, non-steroidal anti-inflammatory drugs, such as celecoxib and diclofenac sodium, can be used to help control inflammation and promote swelling. The above medications should be used under medical supervision. When the arm is squeezed and swollen, if it is not relieved for a long time or the pain worsens, etc., it is recommended to consult a doctor in time to avoid delaying the condition.
