Services
Pain Management
Our comprehensive pain management services address chronic conditions like fibromyalgia, nerve damage, and arthritic joints through personalized treatment plans. We combine board-certified expertise with advanced interventions such as spinal cord stimulators and radiofrequency ablation. Patients receive compassionate care focused on improving quality of life through both surgical and non-surgical approaches.
Regenerative Medicine
Regenerative medicine options harness the body's natural healing processes to treat chronic pain conditions. This innovative approach includes stem cell injections and platelet-rich plasma therapy for patients with joint degeneration or soft tissue injuries. Our physicians evaluate candidacy for these treatments during comprehensive consultations.
Radiofrequency Ablation
Radiofrequency ablation provides long-term pain relief by targeting specific nerve pathways. We use this technique for conditions like facet joint pain and trigeminal neuralgia. The procedure involves precise application of heat energy to disrupt pain signals, offering patients reduced medication dependence and improved mobility.
Spinal Cord Stimulation
Spinal cord stimulation uses implantable devices to manage chronic back and limb pain. Our specialists program these systems to deliver mild electrical impulses that mask pain signals. This reversible treatment option is particularly effective for patients who haven't responded to other therapies.
Nerve Block Injections
Targeted nerve block injections provide diagnostic and therapeutic benefits for various pain conditions. We administer these under imaging guidance to ensure accuracy for conditions like carpal tunnel syndrome and complex regional pain syndrome. Treatments include both temporary and long-lasting formulations.

Report
I have been going to Dr Greenspan who is upfront about getting relief from the excruciating pain I was suffering from. The first three Epidurals did very little for me but the first one of the second round did the trick and I have been completely pain free for 6 weeks. I have to mention the ladies at the front desk are wonderful and caring. Dr. Greenspan is very gentle and I feel like I have my life back being able to do the everyday things. Thanks Doc

Doctors and nurses there are nice but the phone staff is awful. Disrespectful, zero compassion or understanding and if you ask any questions about cost and you will be met with defensiveness and attitude. Now that DR. Lehn left I'm never going back.

Report
I was referred to The American Pain Institute by my Primary Care Physician in early 2020. I have been taking opiate pain medication for re-occurring chronic pain for over 30 years, due mainly to global, severe, advanced, degenerative osteoarthritis. I found Dr. Lehn and his support staff to be very professional and effective while helping me to manage my pain and look ahead to the future. As Dr.Lehn put it, "you've done alright for the past 20 years and I'd like to help you do alright for the next 20". Dr. Lehn helped me to taper down the pain medication I had been taking for

I am a pretty non tech savvy individual and I apologize beforehand. When do you call family family when the arent your biological mother,father, grandparents, sister, brother, aunt, uncle?? The list can go on. Not going into my history, however I am a vet that the VA through Community Care allows me to see Dr Greenspan and his staff at a moments notice. I have had trauma that has left me disabled physically and emotionally. American Pain Institute has done everything they can for my PTSD and Pain that has allowed me to sleep easier, walk easier, function easier and most of all finally want
