Pulled Hamstring or Calf Strain in Hinsdale? How Winback TECAR and Class IV Laser Help Muscle Strains Heal

Short answer: Most hamstring and calf strains heal without surgery, but how you treat the first few weeks makes a big difference to how fast you get back to running, golf, or pickleball, and whether it happens again. At Adisi Health Center in Hinsdale, Dr. Steve Petzel treats muscle strains with Winback TECAR therapy, which creates deep warmth inside the injured muscle, and the 40-watt LightForce XLi Class IV laser, plus a step-by-step strengthening plan. A 2026 randomized trial found a single TECAR session eased pain and improved function in athletes with a fresh hamstring injury more than rest did. Call (630) 887-1900 or schedule an appointment.

What is a hamstring or calf strain?

A strain is a stretch or tear in the muscle fibers, usually where the muscle blends into its tendon. Hamstring strains often happen when you sprint, kick, or reach for a low ball. Calf strains (sometimes called “tennis leg”) often happen when you push off suddenly, like lunging for a drop shot or running up a hill.

Common signs include:

• A sudden sharp pain or a “grab” in the back of the thigh or calf
• Pain when you walk fast, climb stairs, or bend forward
• Tightness and tenderness over one spot in the muscle
• Swelling or bruising that shows up over the next day or two
• Weakness when you try to push off or curl your heel toward your buttock

We see these injuries in runners, soccer and pickleball players, weekend golfers, and people who simply slipped on a step.

How long does a pulled hamstring take to heal?

It depends on how badly the muscle is torn. A mild strain may settle in a couple of weeks, while a bigger tear can take much longer. The most common mistake is going back too soon, because a hamstring that still feels tight and weak is easy to re-injure. That’s why every plan at Adisi pairs treatment with gradual strengthening and a clear return-to-sport plan.

How does Winback TECAR therapy help a strained muscle?

TECAR stands for Transfer of Capacitive and Resistive Energy. It uses radiofrequency energy to create heat from inside the tissue, not on the skin. Our TECAR page lists muscle strains and hamstring tears among the injuries it’s used for. It has two modes:

• Capacitive mode warms the muscle belly and the fascia around it, to boost circulation and help clear swelling.
• Resistive mode reaches denser tissue, like the tendon where the muscle attaches.

Sessions take 12 to 20 minutes and feel like a comfortable, deepening warmth. There’s no downtime, so you can walk out and go about your day. Adisi Health Center is the only Winback TECAR provider in the western Chicago suburbs.

Where does Class IV laser fit in?

The 40-watt LightForce XLi Class IV laser uses high-powered infrared light (photobiomodulation) to calm pain and inflammation and support tissue repair. Laser sessions take about 10 to 15 minutes per area. Dr. Petzel often combines laser and TECAR in the same visit, and shockwave therapy may be added when a strain has turned into a stubborn, long-term tendon problem, such as pain high in the hamstring where you sit.

What does the research say?

Research on TECAR for muscle injuries is still growing, but recent studies are encouraging:

• TECAR for acute hamstring injuries (2026 randomized trial). Researchers in Greece studied 75 young athletes within 5 days of a hamstring injury. One 20-minute TECAR session cut pain by roughly 39% to 63% over the next 48 hours, compared with about 3% to 10% in athletes told to rest. The TECAR group also had bigger gains in function and hamstring flexibility than the rest group and a group treated with TENS (Kelli et al., Sports Medicine and Health Science, 2026; PubMed 41737595).
• TECAR for muscle recovery after hard exercise (2025). In a randomized study of 41 active young adults, TECAR helped thigh muscles recover their normal responsiveness after strenuous exercise designed to cause muscle fatigue, with a modest but consistent advantage in restoring how the muscle fires and behaves (Oleksy et al., Journal of Clinical Medicine, 2025; PubMed 41010853).

These are short-term studies, results vary from person to person, and strengthening exercise remains the backbone of recovery.

What does a muscle strain visit at Adisi look like?

1. Free phone consultation. A 20-minute call with Dr. Petzel to see if you’re a good fit.
2. New patient evaluation ($249, about 45 minutes). A full history and hands-on exam of the injured muscle, plus your low back, hip, knee, and ankle, and your first treatment. Dr. Petzel checks how severe the strain is and whether anything else is contributing, like back-related leg pain.
3. Targeted treatment. TECAR (12 to 20 minutes) and laser (10 to 15 minutes per area), combined as needed. You see Dr. Petzel at every visit.
4. Home program. Gentle range-of-motion work early on, then progressive strengthening for the hamstrings or calves.
5. Return to sport. Dr. Petzel adjusts your plan as you improve and helps you decide when it’s safe to sprint, swing, or play again.

Is TECAR and laser treatment safe?

For most people, yes. Both are non-invasive, with no needles or medication, and Dr. Petzel reviews your health history first.

TECAR is generally not used:

• With a pacemaker or other implanted electronic device
• During pregnancy
• Over a known or suspected tumor or cancer
• Over an active infection, open wound, or skin with reduced sensation
• Over metal implants in the treatment area, unless cleared first

Laser is not used over active cancer, directly over the eyes, over the thyroid, or over the abdomen during the first trimester of pregnancy. Protective eyewear is always worn. Tell Dr. Petzel if you take medication that makes you sensitive to light.

When should I see a physician first?

Get medical care first if:

• You felt a pop high in the back of the thigh near the buttock, followed by large bruising or trouble walking (the tendon may have pulled off the bone)
• You felt a snap at the back of the heel, or can’t push up onto your toes (possible Achilles rupture)
• Your calf is swollen, warm, and red without a clear injury, especially after a long flight, car trip, or surgery. This can be a blood clot, so go to urgent care or the ER.
• You can’t put weight on the leg, or you have numbness or weakness in the foot

If your strain happened in a car accident or at work, we also handle personal injury and auto accident care and workers’ compensation cases. Dr. Petzel will tell you honestly if you need imaging or a surgical opinion.

Frequently asked questions

Should I use heat or ice on a pulled hamstring?
In the first day or two, gentle movement and relative rest matter more than either one. Dr. Petzel will tell you what to do at home based on your exam. TECAR is different from a heating pad because it warms the muscle from the inside under supervision.

Can I keep running with a calf strain?
Usually not right away. Running through a strain often turns a small tear into a bigger one. Most people can walk, bike, or swim gently while they heal, and you’ll get a clear plan for when to run again.

How many sessions will I need?
It depends on the size and age of the strain. Many patients come once or twice a week for a few weeks. Dr. Petzel adjusts the plan as you improve.

Does TECAR hurt?
No. Patients describe a comfortable, penetrating warmth, and there’s no downtime afterward.

Why does my hamstring keep getting re-injured?
Common reasons are returning too soon, leftover weakness, and stiffness in the low back or hips. Your plan includes strengthening and a check of those areas.

Do you see patients from outside Hinsdale?
Yes. Patients come to our office at 534 Chestnut Street, Suite 240 in downtown Hinsdale from Oak Brook, Burr Ridge, Clarendon Hills, Western Springs, Downers Grove, Westmont, La Grange, and nearby towns. See our local pages for Burr Ridge, Clarendon Hills, and Western Springs.
