Reflex Sympathetic Dystrophy (RSD), also known as Complex Regional Pain Syndrome (CRPS), is a chronic pain condition that can occur after injury, surgery, or trauma.
Hyperbaric Oxygen Therapy (HBOT) is a supportive treatment that delivers 100% oxygen in a pressurized chamber, increasing oxygen levels in damaged tissues and helping improve circulation, reduce inflammation, and support nerve healing.
Many patients with CRPS use hyperbaric therapy to help:
- reduce chronic pain
- decrease swelling
- improve mobility
- support nerve repair
Living with Reflex Sympathetic Dystrophy (RSD) — clinically known as Complex Regional Pain Syndrome (CRPS) — means enduring relentless burning pain, debilitating swelling, and chronic nerve pain that conventional medicine rarely resolves. For patients searching for effective reflex sympathetic dystrophy treatment options that go beyond opioids, Hyperbaric Centers of Florida offers a powerful, non-invasive CRPS treatment: Hyperbaric Oxygen Therapy (HBOT). Our clinic in Zephyrhills, FL has delivered over 60,000 treatments since 2003, helping RSD and CRPS patients across the Tampa Bay area and all of Florida find lasting CRPS pain relief — without surgery and without dependency on narcotics.
As a leading RSD treatment center in Florida, we specialize in HBOT for RSD treatment and CRPS treatment with hyperbaric oxygen using real 3 ATA medical-grade chambers — the gold standard in hyperbaric therapy for RSD. If you are looking for a CRPS clinic near you in Florida with decades of proven experience, you have come to the right place.
What Is Reflex Sympathetic Dystrophy (RSD / CRPS)?
Reflex Sympathetic Dystrophy (RSD) is the former clinical name for Complex Regional Pain Syndrome (CRPS) — a chronic neuroinflammatory disorder that produces severe, persistent pain far disproportionate to the original injury. It most commonly develops following a fracture, surgery, sprain, or soft-tissue trauma, and primarily affects the arms, legs, hands, and feet.
CRPS is divided into two subtypes with distinct reflex sympathetic dystrophy treatment options: CRPS Type 1 (the former RSD diagnosis) occurs without confirmed nerve injury, while CRPS Type 2 (formerly Causalgia) follows documented nerve damage. Both subtypes cause the same devastating range of symptoms and both respond to hyperbaric oxygen therapy for CRPS. The condition is also classified as involving sympathetically maintained pain (SMP) or sympathetically independent pain (SIP), though HBOT research shows efficacy across both presentations.
RSD/CRPS affects approximately 75% women, with most patients in their 30s or 40s. Without early and effective treatment, the condition can progress to permanent tissue damage, skin ulceration, and in severe cases, amputation of the affected limb.
Common RSD / CRPS Symptoms That HBOT Addresses
- Intense burning or stabbing pain — a hallmark of chronic nerve pain treatment need
- Swelling, edema, and inflammation in the affected limb — reduced through tissue oxygenation therapy
- Allodynia (severe pain from light touch) — a primary target of allodynia treatment via HBOT
- Skin color changes — mottled, pale, or reddish discoloration
- Abnormal skin temperature — affected area feels unusually hot or cold
- Excessive or reduced sweating (hyperhidrosis or anhidrosis)
- Neuropathic pain and hypersensitivity — addressing neuropathic pain relief is a core HBOT benefit
- Muscle weakness and atrophy from disuse
- Limited range of motion and joint stiffness
- Sleep disruption and severe chronic fatigue
- Depression and cognitive difficulties — often called “brain fog”
How Does Hyperbaric Oxygen Therapy Treat RSD and CRPS?
HBOT for RSD treatment works by delivering 100% pure medical-grade oxygen at up to 3 ATA (atmospheres absolute) of pressure inside a certified hyperbaric chamber. This tissue oxygenation therapy floods damaged nerves and oxygen-starved tissues with the healing oxygen needed to interrupt the chronic inflammation cycle at the cellular level — making it one of the most effective non-invasive CRPS treatment approaches available today.
1. Breaks the Hypoxia-Inflammation Pain Cycle
RSD/CRPS begins when reduced capillary blood flow causes tissue hypoxia — oxygen starvation — which drives inflammation, nerve sensitization, and the relentless burning pain cycle. Hyperbaric therapy for RSD directly corrects this root cause by restoring tissue oxygen levels, cutting off the cycle at its source. This is precisely how HBOT breaks the RSD pain cycle: normalizing local tissue pH and oxygen tension stops the abnormal sensory nerve stimulation that perpetuates RSD.
2. Reduces Neurogenic Inflammation
Increased oxygen tension reduces the inflammatory mediators that drive sympathetically maintained pain, calming the abnormal efferent vasomotor activity that sustains the RSD pain loop. This anti-inflammatory effect is one reason HBOT reduce nerve pain in RSD patients consistently, and it contributes directly to neuropathic pain relief in both CRPS Type 1 and CRPS Type 2.
3. Promotes Angiogenesis and Restores Circulation
HBOT triggers the formation of new blood vessels — a process called angiogenesis — in hypoxic, RSD-damaged tissues. This angiogenesis HBOT effect restores healthy circulation to oxygen-starved limbs and nerves, directly enabling the tissue healing that chronic nerve pain treatment alone cannot provide.
4. Supports Neuroplasticity
HBOT encourages the brain and peripheral nervous system to form new, healthier nerve connections — a process known as neuroplasticity. This neuroplasticity hyperbaric oxygen effect reduces the hypersensitivity and allodynia that define CRPS, and helps explain why patients report improvements in cognitive clarity and mood alongside physical pain reduction.
5. Reduces Fibrous Tissue and Restores Mobility
By reducing inflammation and restoring circulation, hyperbaric oxygen therapy for CRPS decreases fibrous tissue formation in affected areas — directly improving mobility, range of motion, and muscle strength. As swelling diminishes, patients are able to engage in physical therapy with markedly better results.
6. Mobilizes Stem Cells for Repair
HBOT increases circulating stem cells in the bloodstream, which migrate to damaged tissues and contribute to cellular regeneration and nerve repair in CRPS-affected areas, further extending the duration and depth of recovery.

How Hyperbaric Oxygen Therapy Relieves RSD Symptoms
HBOT delivers 100% pure oxygen under increased atmospheric pressure — flooding damaged nerves and tissues with the healing oxygen they need to recover at the cellular level.
Reduces Inflammation
HBOT directly decreases inflammation and edema in tissues affected by RSD, addressing one of the core drivers of the chronic pain cycle.
Restores Blood Flow
Increased oxygen tension improves circulation to oxygen-starved limbs and nerves damaged by the RSD process, actively promoting healing.
Calms Nerve Signals
Normalizing local tissue oxygen and pH levels stops the abnormal sensory nerve stimulation that causes the RSD pain cycle to perpetuate itself.
Reduces Fibrous Tissue
Improved circulation and reduced inflammation work together to decrease fibrous tissue formation, improving mobility and reducing stiffness.
Enables Physical Therapy
As swelling diminishes, patients become able to engage in physical therapy with marked improvements in muscle strength and function.
Restores Sleep & Clarity
Many patients report their first full night of sleep within a few treatments, along with reduced depression and improved mental clarity.
Frequently Asked Questions About HBOT for RSD
Yes. With over 50 years of HBOT experience, we know the therapy is safe and will not worsen your RSD. It is a non-invasive, well-tolerated treatment supervised by our medical team throughout.
Yes. Multiple peer-reviewed studies confirm that hyperbaric therapy for RSD reduces pain, edema, and improves range of motion by restoring tissue oxygen levels and breaking the hypoxia-driven pain cycle. At Hyperbaric Centers of Florida, most patients report measurable improvement within early sessions.
While every patient is different, a series of 40 HBOT treatments is the standard protocol for RSD. If significant improvement is noted, additional sessions may be recommended for optimal and lasting results.
Many patients report improved sleep and reduced pain after just a few sessions. More significant improvements in swelling, mobility, and mental clarity are typically observed across the full treatment series.
Most RSD sufferers report a decreased need for narcotic pain relievers following HBOT treatment. This is one of the most significant quality-of-life benefits our patients consistently experience.
No. HBOT can be beneficial even in long-standing RSD cases. The original injury may have occurred weeks, months, or years prior — we encourage patients to consult with us regardless of duration.
RSD (Reflex Sympathetic Dystrophy) is the older name for Complex Regional Pain Syndrome (CRPS). They refer to the same condition. CRPS Type 1 equals former RSD; CRPS Type 2 equals former Causalgia with confirmed nerve injury. Both respond to HBOT. We treat both at our Florida clinic.
