That stab when you grip, swing, or dink is often tendinopathy at the elbow—not a problem ice alone can fix. Tennis elbow, golfer's elbow, and pickleball elbow share the same underlying issue in slightly different places. Red and near-infrared light therapy is studied for reducing inflammation and supporting tendon repair where blood flow is limited.
The pain is in your elbow. The damage is in your tendon. That stab when you grip a club, racket, or paddle often traces to inflamed tissue at the medial or lateral epicondyle—and ice, rest, and braces alone rarely deliver what tendons need: circulation, oxygen, and repair signals at the cellular level.

Three names. One injury pattern.
Tennis elbow
Lateral epicondylitis
Pain on the outside of the elbow. Triggered by repeated wrist extension—backhands, gripping, lifting with palm down.
~50% of tennis players
Golfer's elbow
Medial epicondylitis
Pain on the inside of the elbow. From wrist flexion and gripping—a hard swing, a fat shot, throwing, or hammering.
~60% of golfers by 50
Pickleball elbow
Mixed lateral / medial
Fast wrist snaps on dinks, drives, and resets load both sides of the elbow. One of the fastest-growing tendinopathies in racket sports.

Where the tendon attaches
Outer side
Lateral epicondyle
Where wrist extensor tendons attach—the home of tennis elbow. Backhands and pronated gripping pull here.
Inner side
Medial epicondyle
Where wrist flexor and pronator tendons attach—the home of golfer's elbow. Gripping and rotating through impact load here.
Why elbow pain sticks around
- 01
Tendons barely get blood flow
Unlike muscle, tendons have minimal circulation. A strained elbow tendon can linger for months or years while muscle injuries heal in weeks.
- 02
Wrist rotation concentrates load
Pronation (palm down) and supination (palm up) under tension focus force at the tendon's bony attachment. Thousands of reps create microscopic tears.
- 03
Inflammation becomes chronic
Without proper repair signals, the body may lay down disorganized scar tissue. The area stays inflamed, weak, and pain-sensitized.
The pronation–supination problem
Forearm pronation (palm down) and supination (palm up) under load anchor force at the epicondyles—not in the forearm itself. Tennis backhands stress the lateral side. Golf grips and rotation stress the medial side. Pickleball wrist snaps fire both.
Four stretches to release the load
Do these daily—twice on days you play. Pair with red light for best results.
- 1
Wrist extensor stretch
Tennis elbow · outer side
Arm straight in front, palm down. Gently pull fingers down and toward you until you feel a stretch along the top of the forearm. Hold 30 seconds, 3 rounds.
- 2
Wrist flexor stretch
Golfer's elbow · inner side
Arm straight, palm up. Gently pull fingers back toward you until you feel a stretch along the underside of the forearm. Hold 30 seconds, 3 rounds.
- 3
Pronation / supination mobility
Pickleball · both sides
Elbow bent 90°, slow rotations palm-down to palm-up under no resistance. 10 reps each direction to mobilize without loading the tendon.
- 4
Eccentric wrist curl
Tendon rebuilding
Light weight or resistance band—slowly lower the weight from a flexed wrist position (3–5 seconds down). 2 sets of 10–15. Start only when acute pain allows; ask a PT first.
Red light reaches where blood flow is limited
660nm and 850nm wavelengths penetrate skin and soft tissue to reach inflamed tendon. Mitochondria produce more ATP, which may speed repair. Local capillaries may dilate, bringing oxygen and nutrients to a low-circulation structure. Photobiomodulation for lateral and medial epicondylopathy is reported in journals including Lasers in Medical Science and the British Journal of Sports Medicine.
660nm
Red light · surface inflammation
May reduce inflammatory signaling in superficial tendon and surrounding tissue.
850nm
Near-infrared · deep tendon repair
Penetrates deeper to reach tendon tissue and support mitochondrial ATP production.
What to expect week by week
- Day 1
The cellular spark
Photons reach inflamed tendon tissue. Mitochondria ramp up ATP production and localized blood flow may increase. A subtle warmth is normal; dramatic relief is rare on day one.
- Week 1
Less morning stiffness
Many people notice reduced post-activity soreness within 7–10 days of consistent sessions.
- Weeks 2–4
Pain eases with activity
Gripping, swinging, and daily tasks may feel less sharp. Inflammation often calms before full tendon remodeling.
- Weeks 4–8
Real tendon remodeling
Collagen organization and strength gains typically need a month or more of consistent photobiomodulation.
- Week 12
Return to sport
Many athletes resume full play timelines here—but progress varies. Severe cases need longer and professional guidance.
Recovery at Sauna Hut
Our full-body red light bed delivers 660nm and 850nm in sessions of up to 20 minutes. During your visit, position the affected forearm and elbow toward the panel array so the painful epicondyle and muscle belly receive direct exposure.
Suggested stack for Green Lake athletes:
- Run through the stretches above before or after your session
- Book red light 2–3× weekly for 4–8 weeks during active recovery
- Add therapeutic massage for forearm and grip tension feeding the tendon
- Infrared sauna after play may further support circulation and soreness
Consistency beats intensity—daily or near-daily light exposure for several weeks outperforms occasional long sessions for chronic tendinopathy. See a sports medicine provider for severe pain, numbness, or loss of grip strength.
How common treatments compare
| Approach | Typical cost | Healing focus | Tradeoffs |
|---|---|---|---|
| Red light therapy | Per-session or package | Cellular repair signals | Minimal at clinical doses |
| Cortisone shots | $200–500+ per injection | Short-term relief; may weaken tendon | Limited lifetime use |
| NSAIDs / ice | Ongoing | Symptom management | Masks pain; no tendon repair |
| Bracing | Low | Load reduction only | Does not fix tendon |
| Physical therapy | Varies; often covered | Eccentric loading + rehab | Requires consistency |
| PRP / surgery | High | Invasive options for chronic cases | Downtime, variable outcomes |
Common questions
- How fast will I feel a difference?
- Less stiffness and post-activity soreness often appear within 7–10 days. Meaningful tendon remodeling typically takes 4–8 weeks of consistent sessions. Tendons heal slowly—light may accelerate what your body is already attempting.
- Can I keep playing through the pain?
- Many athletes use photobiomodulation after matches to manage inflammation. If pain is severe or grip strength drops, see a sports medicine physician before continuing play.
- Is daily use safe?
- Red light at clinical doses is generally safe for daily use with no drug interactions. Consistency matters more than intensity of any single session.
- Will it replace cortisone or surgery?
- It's a healing support tool, not a numbing agent. Many clinicians recommend photobiomodulation before invasive options—but follow your physician's guidance.
- Tennis vs. golfer's elbow—which side do I treat?
- Tennis elbow: outer (lateral) epicondyle. Golfer's elbow: inner (medial) epicondyle. Pickleball may need both. Direct light toward the painful attachment and along the forearm muscle belly.
