This study will investigate the effectiveness of repeated ozone therapy combined with splint therapy for carpal tunnel syndrome (CTS).CTS patients will be split into two groups: ozone plus splint and splint only. Both groups will use wrist splints for 3 weeks, with the ozone+splint group receiving weekly ozone injections for three weeks.

Inclusion Criteria:

• being 18-65 years, with mil-modarete CTS, symptoms continued for at least 3 months

Exclusion Criteria:

• hand edema or prior injections, thenar atrophy, prior CTS surgery, severe EMG results, recent physical therapy, steroids, or platelet-rich plasma for CTS in the past year, and conditions causing secondary CTS (e.g., thyroid disorders, diabetes, pregnancy, rheumatoid arthritis, Dupuytren's contracture, inflammatory arthritis, connective tissue diseases). Also excluded: neck or arm pain conditions (e.g., cervical disc herniation, wrist fracture, proximal upper extremity entrapment neuropathy, polyneuropathy, peripheral nerve damage, fibromyalgia), history of G6PD deficiency, uncontrolled hyperthyroidism, thrombocytopenia, and contraindications to general ozone therapy (e.g., ACE inhibitors for severe cardiovascular instability).
