What Happens During the Visit
- Musculoskeletal ultrasound of joints, muscles, tendons, and peripheral nerves — performed by Dr. Mazin during the consultation, so you get the diagnosis and treatment plan in the same visit
- Ultrasound-guided injections — therapeutic blocks and targeted delivery of medication into joints and periarticular soft tissue
- Regenerative therapies — platelet-rich plasma (PRP) therapy and hyaluronic acid injections (viscosupplementation) for osteoarthritis and chronic tendinopathies
Important: Dr. Mazin only prescribes PRP, hyaluronic acid, and other injectable procedures after a clinical examination and review of ultrasound or MRI findings. If you haven't been seen yet, please start by booking a consultation.
