Dr. Barrett Johnston was born in New Orleans, Louisiana and is a graduate of California Polytechnic State University.

He obtained his medical degree at Louisiana State University in New Orleans. His anesthesia residency and pain fellowship were both completed at Harvard's School of Medicine at Brigham and Women's Hospital in Boston, Massachusetts. Following his training, Dr. Johnston returned to Louisiana and founded Interventional Pain Institute in Baton Rouge.
Services
Conscious sedation is a type of anesthesia that makes the patient feel very relaxed. It reduces painful sensations and the awareness of pain. It is not intended to put the patient to sleep, and will wear off quickly after a procedure. Conscious sedation is commonly used for simple procedures that can be completed quickly.
This injection procedure is performed to treat the pain of an inflamed nerve in your spine. If you have a herniated disc, spinal stenosis, or some other problem that is pressing on a nerve, it may help you. Steroid medication can reduce the swelling and inflammation caused by spinal conditions. The steroid medication is injected into the epidural space, which is the space around the inflamed nerve.

Appointments are always running late and they don't seem to know what is going on with the patients. It was a much better experience before they moved to Summa

Just FYI no pain doctor will just give you pain meds because your in pain. If your MRI are CT Scan doesn’t show good reason why you’re in pain the doctor can’t legally just give you medicine because you say your in pain!!!!’ I really don’t think people understand how pain doctor work . These doctors can and do loose there license if they give you pain meds and there’s no medical test showing that you need it!!!!! One big no no never go to a pain doctor asking for more meds!!!! Pain management is to minimize the pain Not take all your pain away!!!! The pain doctors that listen to the

Dr. Johnston and his staff have been wonderful to me for the past 3 years. They go above and beyond to help me live comfortably and safely. I appreciate the fact that they are attentive to me when I have questions and protective of my safety concerning prescribing meds.

Dr. Barrett Jonhston is the worst Doctor anyone can see. Today I had an appointment with him and I waited for more than 1 hour, then when he saw me and asked me how I felt and told him that I was in a lot of pain and then ask me how I was with the medication and when I told him that he know that I need something stronger, then he got angry and told me that I had to see another doctor because I had been very aggressive with him. That is completely false. I do not recommend anyone to see Dr. Barrett Jonhston not waste your time. Please educate yourself or change your profession.

Dr. Barrett Joshnston is the worst doctor I have ever had the displeasure of seeing. From my very first visit he belittled me and acted like I was some kind of drug addict. He told me that i don’t need to be on any pain medicine. I’ve had three back surgeries, my last being a spinal fusion and I currently have two tears in the discs above my fusion and a herniated and bulging disc that may require a 4th surgery later on. He was very rude and acted like he didn’t have time to discuss anything with me. Basically rushed me out because he had too many patients that needed his help, ( I guess

My visits with the staff has always been helpful. I am explained about my situation and heard out about my progress as well as no progress. At times the medical room wait can be up to 30 mins, but overall it’s worth it. I appreciate all explanations, treatments and paper information.
Thanks to the team .

Dr. Barrett Johnston,made my two visits there absolutely rushed & uncomfortable! I have never bn treated like he did me. he belittled me & I was getting spinal & cervical injections. I was scared & not remembered all we had talked about the prior week. they were going to inject me without me even seeing him so I could ask questions & voice my concerns about my previous visit where I felt rushed & unclear afterwards. when he finally came into the room I was in(only bc I demanded to speak with him before my procedure) I started to ask him questions about what he was going to do & he told me straight

Dr. Johnston is a kind passionate smart docter. His beautiful office is located off of bluebonnette. I have never met a kinder staff the one here. Don’t make a mistake and go to any other pain docter. This is the ultimate type of docter we all search for. He is the type of docter you can tell the truth to and know he will still make sure your not suffering.
He is not only ahead of his time he’s a downright genuise. He deserves much credit.

I have been seeing Dr. Johnston for a couple of years. He got my pain completely under control.Now, I just see Dr. Johnston for injections that really seem to help. I was in horrific pain before and couldnt live a “normal” life. Dr. Johnston truly cares about his patients and their pain! I’m so glad I found him when I did. His office and nursing staff are awesome too!
