What we treat, head to toe
Concussion to plantar fasciitis, frozen shoulder to slipping ribs. If you are not sure whether we treat your pain, start here.
Most of our patients have already seen someone
Patients often tell us they didn’t know a clinic like ours existed, or they assumed we only treat one thing. Our name has the word fascia in it, and that leaves people wondering whether their shoulder, their tailbone, or their headaches count.
They usually do. Fascia is the connective tissue that wraps and links every muscle, nerve, tendon, and organ, and it is richly supplied with nerves.1 It can thicken, stiffen, and stop gliding,2,3 and that can hurt in ways an MRI or X-ray doesn’t show. Disc and joint “wear” on a scan, meanwhile, is common in people who have no pain at all.4 So a normal-looking scan doesn’t mean nothing is wrong, and an abnormal one doesn’t always explain the pain.
At The Fascia Institute and Treatment Center of LA, Dr. Jacques Courseault, a board-certified physical medicine and rehabilitation physician, uses ultrasound to look at the soft tissue while it moves. Then he treats what he finds: fascia, ligament, tendon, muscle, or nerve. The list below is what that covers, organized by body region. Each item links to a deeper page where we have one.
Head, face & neck
Upper back, shoulder blades & ribs
Shoulder & upper arm
Elbow, wrist & hand
Abdominal wall, pelvis & tailbone
Low back, buttock & hip
Thigh & knee
Lower leg, ankle & foot
Whole body & connective tissue
Scars & after surgery
Same approach, whatever hurts
Map it
A physician-performed ultrasound exam of the painful area, or a full-body Fascial Map if the pain is widespread. Fascial Mapping is optional, not a requirement for treatment. Labs and FIT GPS genomic screening are added when metabolism or healing may be part of the problem.
Treat it
Treatment is matched to the tissue we find: Hydrofascia Release™ for stuck fascia and nerves, prolotherapy or PRP for weak ligaments and tendons, and shockwave or TECAR for tissue that needs a push to heal.
Keep it
Monthly in-person visits during Dr. Courseault’s Beverly Hills weeks, with PEMF and red light therapy available between visits, and strength work to keep the problem from coming back.
Every treatment, in one place
This list isn’t everything
If you have pain in muscle, tendon, ligament, fascia, or a nerve that hasn’t been explained or hasn’t gotten better, we want to hear about it, even if it isn’t on this page. Call (424) 378-3488 or send us a message describing what’s going on.
If it isn’t something we treat, we’ll say so and point you to the right specialist.
Have out-of-network benefits? You may get money back.
FIT LA is an out-of-network practice. Many PPO plans still reimburse part of the cost of out-of-network care, but the claim forms put a lot of people off.
So we pay for Reimbursify, a service that submits your visits to your insurance company for reimbursement. You don’t have to fill out the claim forms yourself.
How much you get back depends on your plan, your deductible, and your out-of-network benefits; some plans pay nothing out of network, and reimbursement is never guaranteed. Call the number on your insurance card and ask about out-of-network benefits before your visit. See how out-of-network reimbursement works and our pricing.
Go to urgent care or the ER first if you have:
- Chest pain, pressure, or shortness of breath, even if you think it’s “just a rib”
- Sudden, severe, or worsening belly pain, or belly pain with fever or vomiting
- New weakness, a foot that drops, or loss of bowel or bladder control
- Fever with back or joint pain, or a joint that is hot, red, and swollen
- Pain after a major fall or accident, or a concussion with worsening headache, repeated vomiting, or confusion
We treat soft-tissue pain. Fractures, infections, emergencies, and conditions that need surgery belong elsewhere first.
Find out what’s actually causing your pain
A physician-performed ultrasound evaluation, a clear explanation of what we find, and a plan matched to the tissue. Five to ten minutes from Century City; patients travel to us from across California and beyond.
Have out-of-network benefits? We pay for Reimbursify to submit your visits to your insurer for possible reimbursement.
Frequently asked questions
What does a fascia doctor treat?
Pain that comes from soft tissue: fascia, muscle, tendon, ligament, and the nerves that run through them. That covers neck and back pain, shoulder, elbow, hip, knee, and foot problems, nerve entrapments, painful scars, and the widespread pain that often comes with hypermobility. At FIT LA, the physician is Dr. Jacques Courseault, who is board-certified in physical medicine and rehabilitation.
Do I need a diagnosis or a referral to book?
No. Many patients come to us precisely because they don’t have a clear diagnosis yet. Bring any imaging, reports, and a list of what you’ve already tried.
My MRI or X-ray was normal. Can you still help?
Often, yes. Standard scans are good at showing bone, discs, and large tears, but they are taken while you lie still. Ultrasound lets us watch fascia, tendons, and nerves move, and changes in the fascia have been measured this way in people with chronic pain.2
Do I need a full-body Fascial Map first?
No. A Fascial Map is optional. It’s most useful when pain is in many places or you’re an athlete with years of accumulated load. If you have one problem area, we can start there.
Do you only treat athletes?
No. We treat professional and college athletes, but most of our patients are people whose pain is affecting work, sleep, or daily life, including many hypermobile patients, surgical patients, and first responders.
My condition isn’t on this list. Should I still contact you?
Yes. Call (424) 378-3488 or message us. If it isn’t something we treat, we’ll tell you and suggest who to see.
Do you take insurance?
We are an out-of-network practice, and our pricing is published. If your plan has out-of-network benefits (common with PPO plans), you may be able to get part of your visit cost reimbursed. We pay for Reimbursify, a claims service that submits your visits to your insurance company for reimbursement, so you don’t have to file the paperwork yourself. How much comes back depends entirely on your plan and deductible, and some plans pay nothing out of network, so call your insurer to check your out-of-network benefits before your visit.
Can I come from outside Los Angeles?
Yes. Patients travel to Beverly Hills from around the country, and The Fascia Institute also has a flagship clinic in New Orleans.
