Poking your finger while playing soccer results in a swollen joint that requires immediate cessation of the sport and braking of the finger. The finger can usually be immobilized with a small splint to prevent movement of the joint. Cold compresses can be applied locally, usually using cool mineral water to ice the affected area for 20 minutes, 4-6 times a day. Cold compresses can promote capillary contraction, reduce bleeding and decrease joint swelling. If the pain is more obvious, you can take oral non-steroidal anti-inflammatory drugs for analgesic treatment, for example, you can take oral Fitalin extended-release tablets, ibuprofen capsules and so on. In addition, local physical therapy, such as radiofrequency, microwave and other therapeutic measures, can help reduce joint swelling. 48 hours later, it is necessary to stop the cold compresses and replace them with local hot compresses, in order to improve local blood circulation, and promote the reduction of joint swelling.
