Got my backhand back.
Two cortisone shots and 18 months of bracing did nothing. Started Spark in March — within a month I was hitting backhands without flinching for the first time in two years. Not even kidding.
Pain-free at 4 weeks
Tennis · Golfer's · Pickleball Elbow
The pain is in your elbow. The damage is in your tendon.
That stab when you grip the racket. The throb after 18 holes. The ache that ruins your dink shot. Your tendons are inflamed — and ice isn't fixing it. 10 minutes a day with red light therapy can.

Same Tendon. Different Sport.
Three names. One injury.
Tennis elbow, golfer's elbow, and pickleball elbow are all the same problem in slightly different places — overworked tendons that anchor to the bony bumps of your elbow.

Tennis Elbow
Lateral epicondylitis
Pain on the outside of your elbow. Triggered by repeated wrist extension — backhands, gripping, lifting with your palm down.
Outer elbow pain60%

Golfer's Elbow
Medial epicondylitis
Pain on the inside of your elbow. From wrist flexion and gripping — a hard swing, a fat shot, throwing, or hammering.
Inner elbow pain#1
fastest-growing injury
Pickleball Elbow
Mixed lateral / medial
The fast wrist snap of dinks, drives, and resets fires both sides of the elbow. The fastest-growing tendinopathy in any sport.
Both sides
Why It Hurts
Your elbow won't just heal.
Most people blame their swing. Their grip. Their paddle. The real culprit is way smaller — and it's why ice, rest, and braces aren't getting you back on the court.
Anatomy of the injury
Outer Side
Lateral Epicondyle
Where your wrist extensor tendons attach. The home of tennis elbow.
Inner Side
Medial Epicondyle
Where your wrist flexor and pronator tendons attach. The home of golfer's elbow.
Three reasons it sticks around.
01
Tendons barely get blood flow
Unlike muscle, your tendons have minimal circulation. That's why a torn quad heals in weeks but a strained elbow tendon can drag on for months — or years.
02
Your wrist rotation is the real load
Every time you pronate (palm down) or supinate (palm up) under tension — that force concentrates at the tendon's bony attachment in the elbow. Thousands of reps later, microscopic tears stack up.
03
Inflammation becomes the new normal
Without proper repair signals, the body lays down disorganized scar tissue instead of strong tendon. The area stays inflamed, weak, and pain-sensitized — sometimes for years.
In Plain English
The Pronation–Supination Problem
Your forearm has two key motions: pronation (palm down) and supination (palm up). Almost every racket sport, golf swing, or paddle stroke is a violent version of one or both.
The muscles that drive those motions don't attach in your forearm. They anchor up at your elbow — at the two bony bumps called the epicondyles.
- Tennis — backhands and lifting in pronation pull the lateral side.
- Golf — gripping and rotating through impact pulls the medial side.
- Pickleball — fast wrist snaps fire both sides at once.
Do This First
Four stretches to release the load.
Pick a stretch. Hit start. We'll count the rounds. Do them daily — twice if you played that day.
Reference
For tennis elbow · outer side
Wrist Extensor Stretch
Extend your arm straight in front of you, palm facing down. With your other hand, gently pull your fingers and hand down and toward you until you feel a stretch along the top of your forearm. Keep your elbow straight.

The Science
Red light reaches the place blood doesn't.
Red and near-infrared light at the right wavelengths — 660nm and 850nm — penetrate skin and soft tissue to reach the inflamed tendon. Inside the cells, light triggers your mitochondria to produce more ATP, which speeds tissue repair. It also dilates local capillaries, finally bringing oxygen and nutrients to a notoriously low-blood-flow structure.
660nm
Red light · surface inflammation
850nm
Near-IR · deep tendon repair

Per session, once a day
Photobiomodulation for lateral and medial epicondylopathy is supported by peer-reviewed clinical research published in journals including Lasers in Medical Science and the British Journal of Sports Medicine.
12-Week Comeback
What actually happens, week by week.
Tendons heal slowly. Knowing what to expect at each stage is what keeps people from quitting at week 1. Drag through the timeline.
Day 1 · First Session
The cellular spark.
Inside Your Body
660nm and 850nm photons enter your skin and reach the inflamed tendon. Mitochondria absorb the light and immediately ramp up ATP production. Localized blood flow nearly doubles around the elbow.
How You'll Feel
A subtle warmth during the session. Maybe slightly more mobility right after. Nothing dramatic — and that's normal. Most people barely feel anything different yet.
From Someone Who's Been Here
Felt warmth, not much else. Almost stopped after the first session — glad I didn't.
The Protocol
10 minutes. Once a day.
A simple daily routine that combines targeted stretching with red light therapy where it counts. Designed for tennis elbow, golfer's elbow, and pickleball elbow.
10
min
The Daily Elbow Reset
Best done after activity, or in the evening before bed.
0:00 – 2:00
Warm up the joint
10 wrist circles each direction. 10 slow pronation/supination rotations. Loosen the tissue before treatment.
No device
2:00 – 7:00
Targeted red light on the painful tendon
Position Spark or Beam 6 inches from the affected epicondyle (outer for tennis, inner for golfer's, both for pickleball). Stay still. Let the light do the work.

7:00 – 9:00
Treat the muscle belly
Slide the panel down to cover the meatiest part of your forearm — that's where the tension feeding the tendon actually lives.

Finish with a stretch
30-second wrist extensor stretch (tennis side) or wrist flexor stretch (golfer's side). Lock the gain in.

Pro tip: Consistency beats intensity. 10 minutes every day for 3–4 weeks moves the needle on a chronic tendon issue far more than a 30-minute marathon session twice a week.
Real People · Real Recoveries
From skeptic to back on the court.
Played 18 holes pain-free.
My PT recommended I look into red light therapy after my golfer's elbow stalled out. Bought the Spark on a whim. Six weeks later I played 18 holes pain-free for the first time since 2022. Buy. The. Thing.
Back to 18 holes by week 6
Stopped wearing the brace.
Pickleball wrecked my elbow. Wore a brace for a year and still couldn't dink without wincing. Got the Beam because both sides hurt. Five weeks in I realized I'd left my brace in the drawer for three days. That was when I knew.
Brace-free at 5 weeks
Skipped the cortisone shot.
Doctor wanted to give me my third cortisone injection. I told him I'd try the red light first. He said good luck. Eight weeks later I went back and told him I didn't need the shot. He asked which device.
Resolved by week 8
Was about to schedule surgery.
My ortho had me on the surgery schedule. My wife begged me to try one more thing. Three months on Beam and I cancelled the surgery. I still play 4x a week. I'm 62 and I've never felt better in my elbow.
Cancelled surgery at week 12
My doubles partner now wants one.
I was the one who used to ice my elbow between games. Now I show up early, run 10 minutes with the Spark, and play three sets without thinking about it. My doubles partner asked what changed. Now she's ordering one.
Ditched ice by week 3

Common Questions
FAQ
How fast will I feel a difference?
Most users notice less morning stiffness and reduced post-activity soreness within 7–10 days of daily use. Real tendon remodeling — the kind that actually clears the injury — typically takes 4–8 weeks of consistent 10-minute sessions. Tendons repair slowly. Light just speeds the process the body was already trying to run.
Can I use it if I'm still playing through the pain?
Yes — and many users do. The protocol is non-invasive, has no drugs or downtime, and many athletes use it the night of and the morning after a match to keep inflammation in check. That said: if pain is severe or you've lost grip strength, see a sports medicine physician.
Spark or Beam — which one do I actually need?
Spark if you want a portable, joint-sized tool that's perfect for the elbow and easy to bring to the court or course. Beam if you want broader coverage that hits the elbow, forearm, and shoulder in one session, or if you're treating both arms regularly. Many people start with Spark and add Beam later.
Is it safe to use every day?
Yes. Red light therapy at clinical doses is safe for daily use indefinitely. There's no buildup, no drug interaction, no rebound. The bigger risk is not being consistent — chronic tendinopathy responds to volume of treatments, not intensity of any single session.
Will it replace cortisone shots or surgery?
Red light therapy is a long-term healing tool, not a numbing agent. Cortisone masks pain quickly but can weaken tendon tissue over time. Many physicians and PTs now recommend photobiomodulation as a first-line tool before more invasive interventions. Always follow your physician's guidance.
What if it doesn't work for me?
Every Valo device is backed by our 60-day money-back guarantee. Try it daily for 60 days. If you don't notice a real difference in your elbow pain, send it back for a full refund.
Stop ice. Stop braces. Start healing.
Your elbow has been telling you something for months. It's not asking for rest — it's asking for circulation, oxygen, and the right signals to repair. 10 minutes a day. That's all it takes.
