Efficacy of NSAID Peritendinous Injection for Acute Tendinitis

This study evaluates whether NSAID peritendinous or ligament injections at acute sprain sites can relieve pain and restore function. Forty patients will be randomly assigned to either the injection or oral NSAID group. Pain will be assessed subjectively using the Numeric Pain Rating Scale and objectively through pressure pain threshold measurements. Functional outcomes (DASH for the upper limb, FADI for the lower limb) will be evaluated before treatment and at 3 days, 1 week, and 4 weeks post-treatment.
