Dr. Ambalu will be performing procedures in CareMount Medical’s Poughkeepsie Oakwood and Fishkill Westage office procedure suites.

He will be treating patients with back pain, neck pain, headaches, and joint pain, among other conditions. A few of the treatments he offers include:

Epidural injections

Radiofrequency nerve abaltions for the spine, neck, and major joints

Spinal cord stimulation

Endoscopic rhizotomies for low back and hip pain
