Sports medicine injection
Are corticosteroid injections for joint or tendon pain safe, and can they be repeated?
Doctor’s answer
A local corticosteroid injection may provide short-term pain relief for selected cases of arthritis, bursitis, or tenosynovitis. Safety depends on the injection site, dose, and interval. Repeated injections or injections close to a tendon may increase tissue weakening and rupture risk, so the diagnosis should be clear before treatment.

Does PRP injection work for sports injuries, and who may benefit?
The effects of platelet-rich plasma (PRP) vary with the condition, duration of symptoms, and preparation method. Selected patients with chronic tendinopathy or mild-to-moderate joint degeneration may discuss PRP when structured rehabilitation has provided limited relief. Review the strength of evidence, cost, and realistic expectations before treatment.
Can insufficient sleep increase sports injury risk and slow recovery?
Insufficient sleep can reduce reaction speed, attention, and movement control and can interfere with muscle repair, pain regulation, and recovery after training. Athletes should keep a regular schedule and allow enough sleep for their training load. Persistent insomnia, marked daytime sleepiness, or snoring with pauses in breathing warrants assessment.
Should athletes use static stretching or a dynamic warm-up before exercise?
Begin with 5 to 10 minutes of low-intensity activity, followed by a sport-specific dynamic warm-up such as high knees, lunges, leg swings, and progressive accelerations. Longer static stretches are generally better placed after training or in a separate flexibility session.
