“Do I need physical therapy for tennis elbow?”

Yes, it would be a good idea to get this evaluated. Your neck, shoulder, and arm need to be in good alignment for full, pain-free function, and it is not uncommon for "tennis elbow" to reflect confusion throughout the arm.

Tennis elbow is lateral epicondylitis in medical language. It is from inflammation of extensor tendon. Sometimes there might be partial tear. You need to get evaluation from your orthopedic doctor. He will guide you for the treatment. Yes, most of the time it requires physical therapy. If not better then might require MRI and possible injection. See your orthopedic doctor first. Thanks
