Positive results with acupuncture vs massage for tennis elbow or not?

Yes: Although my general treatment is physical therapy, tennis elbow braces, anti-inflammatories, cortisone injections, and rest; i often use massage (especially transverse massage) and many of my patients have had success with acupuncture.

Therapy: I would suggest physical therapy. You can calm your symptoms with modalities such as ultrasound and stim. Then you can work on the appropriate strengthening exercises and stretching to prevent recurrence.
