What Our Patients Will Tell You
Pain Management with an
Intrathecal Pain Pump
Tried everything to manage your pain…
But nothing works?
Want off opioids?
An intrathecal pain pump may be the right treatment for you…
Manage your pain without the stress
– and live again!
Intrathecal pain pump delivery is a proven, safe, and effective therapy for managing chronic pain, and back and neck pain. Dr. Castillo is a leading national expert in pain pump therapy.
The intrathecal pain pump system consists of a pump and catheter surgically placed under the skin.
Unlike oral medications that circulate throughout your bloodstream, an intrathecal pain pump delivery system directly releases medication into the spinal cord, which may lead to fewer side effects.
Many people experience significant improvements in their pain symptoms and quality of life after receiving an intrathecal pain delivery system.
Intrathecal pain pump medication delivery cannot eliminate the source of your pain or cure any underlying disease, but it may help you better manage your pain – getting you back to what you love!

Treating Chronic Pain with Ozone Therapy


Ozone Therapy can increase the immune system response and help with patients’ chronic pain.
What is Ozone Therapy? Ozone is a natural gas known to help individual cells produce energy through their mitochondria. It can increase tissue oxygenation, improves circulation, and cellular rejuvenation.
Ozone Therapy can be used to complement traditional medical treatments. Such as with cancer helping to minimize nausea, fatigue, and even hair loss following chemotherapy. Ozone can increase the immune system response.
It can also help decrease symptoms of other chronic conditions such as Complex Regional Pain Syndrome (CRPS), MS, Parkinson’s disease, and degenerative disc disease.
