The How Clinic in Encinitas is a regenerative-medicine and pain-management practice led by board-certified emergency medicine physician Dr. John How, MD, RMSK, on Garden View Court off North El Camino Real. Precision ultrasound-guided nerve hydrodissection and PRP injection protocols address peripheral-nerve entrapment and soft-tissue injuries using the same diagnostic-imaging pipeline that Gaspar Doctors of Physical Therapy coordinates with for post-procedure rehabilitation. Dr. How earned his MD at Loma Linda University School of Medicine and completed emergency-medicine residency at Ascension St. John Hospital in Michigan before joining the clinical faculty for the primary-care sports-medicine fellowship at UHC SoCal MEC, where he teaches ultrasound-guided diagnosis and regenerative technique. The clinic's integrative team also delivers stellate ganglion block procedures for combat-related PTSD, NAD+ infusion therapy, hormone optimization, and functional-medicine workups, expanding the pain-management corridor that includes acupuncture-based providers such as MK Integrative Wellness. Highest-complexity interventions involve multi-site ultrasound-guided PRP injections targeting articular cartilage defects in the knee, shoulder, and hip combined with hyaluronic-acid viscosupplementation for grade-III osteoarthritic joints.
