Legs tingling after workouts? Your body’s message revealed

As blood circulation increases throughout your body during physical activity, your muscles expand to handle the increased flow. While this aids in supporting you during the exercise, the enlarged muscles may press against nerves and blood vessels, leading to a tingling sensation in your legs following a run or other types of physical exertion.

These typical reasons for calf tingling following physical activity are not the sole factors that could lead to the feeling, nevertheless.

There are numerous reasons for leg tingling, but the first step is to ensure the description is precise, saysMerije T. Chukumerije, MD, a cardiologist with the Cedars-Sinai Medical Network in Beverly Hills, California. Is it a tingling sensation, itching, pain, numbness, or another type of feeling? The specific description is crucial for identifying the underlying cause.

Additionally, it’s important to recognize when the emotion could be more severe and necessitate a visit to the physician.

What leads to that tingling, uneasy sensation in your legs, often called pins and needles? Here, we explore eight possible causes.

1. A Histamine Response

If you experience a burning and scratching sensation in your feet following physical activity, or if it spreads to your buttocks and lower abdomen, it might be due to a histamine reaction.

Yes, it may seem like you’re allergic to physical activity, but don’t put away your running shoes just yet.

The body produces histamine to enhance blood flow during physical activity, according to Dr. Chukumerije. This histamine release leads to a feeling similar to that experienced during an allergic reaction, resulting in an itch in the areas where histamine is most active during exercise, which are the muscles.

2. Circulation Issues

During a vigorous exercise session, a significant portion of your blood is redirected to your active muscles, and your blood vessels dilate to handle the higher volume of circulation.

However, snug shoes or garments may limit your circulation and cause a tingling feeling, particularly if they are tied too tightly or even if they are too loose, saysSteven E. Mayer, MD, a sports medicine doctor at the Northwestern Medicine Running Medicine Clinic in Naperville, Illinois. The same applies to exercise attire if it is too tight and restricts blood flow.

If the tingling or discomfort results from peripheral artery disease, this is attributed to plaque accumulation, or atherosclerosis, in the arteries that block blood flow to the muscles, reducing the nutrients and oxygen available to them, according to Chukumerije.

PAD needs medical care. If you have the symptoms listed, consult your physician for an accurate diagnosis and treatment strategy.

3. Low Electrolytes

Electrolytes such as sodium, potassium, calcium, and magnesium play a role in controlling nerve and muscle activity, maintaining fluid balance, and aiding in the healing of injured tissues.

Physical activity leads to changes in your body’s fluid levels, which may result in electrolyte disturbances and/or dehydration. This can impact the way muscles contract and relax, according to Chukumerije.

Fix It

To maintain proper electrolyte balance before and after exercising, consume sufficient water to remain hydrated. For extended or intense workouts, sports beverages with calcium and potassium can also be beneficial.

For a useful reference, you can try to adhere to these hydration recommendations from theAmerican Council on Exercise:

• 17 to 20 ounces of fluid consumed two to three hours prior to working out
• 8 oz 20 to 30 minutes prior to working out
• 7 to 10 ounces every 10 to 20 minutes while working out
• 8 ounces of water or a sports beverage consumed within 30 minutes following physical activity

4. A Pinched Nerve

Some individuals may experience tingling following physical activity, according to Chukumerije. This occurs because of improperly functioning peripheral nerves, which can transmit incorrect signals to the brain.

If the feeling of nerve pain in the legs following physical activity affects both sides, it’s likely due to an issue in your lower back.

A tingling or numb sensation is frequently combined with pain that extends down both legs, which intensifies when standing and improves when sitting or leaning forward. You may also experience difficulty maintaining balance or notice alterations in bowel or bladder function.

The most frequent nerve-related issue observed after exercise, according to Dr. Mayer, is known as tarsal tunnel syndrome, which involves compression of a nerve at the ankle that extends into the foot.

Fix It

Take a pause from your exercise regimen and schedule a complete medical check-up if your numb legs are troubling you.

Contact your physician if you experience persistent leg tingling after falling during exercise. They can identify the cause of the sensation and determine if it’s due to a compressed nerve, as well as suggest the most effective remedy for the tingling.

5. Back Issues

If numbness is not typically part of your workout routine and you haven’t introduced any new tight-fitting garments into your closet, a sudden occurrence of leg tingling following a walk or other form of exercise might suggest an injury.

Certain individuals are more prone to SI joint injury when they undergo hormonal fluctuations during menstruation or pregnancy, which lead to looser ligaments and increased joint mobility.

Fix It

If the discomfort originates in the lower back, similar to a sciatic nerve issue, we would start with physical therapy, which is typically effective and often resolves the issue, according to Mayer.

However, consult your physician for an assessment rather than ignoring the discomfort when dealing with back injuries. Not addressing an injury properly may lead to additional issues, such as being unable to exercise for several months.

6. A Neuroma

A neuroma develops when a group of nerves in your foot, typically located between the third and fourth toes, becomes swollen.

Another frequent cause of foot tingling during exercise, according to Mayer, is Morton’s neuroma, which occurs when a nerve between the toes becomes compressed.

Fix It

Symptoms can fluctuate. Applying ice can help decrease swelling. Place ice on your feet for 10 to 15 minutes each hour over a period of five to six hours. Additionally, you may use shoe inserts specifically made for neuroma relief, which assist in minimizing irritation while exercising by providing better foot support.

7. Chronic Exercise-Induced Compartment Syndrome

Exertional compartment syndrome, according to Mayer, occurs when the fascia surrounding the muscles becomes tight, leading to muscle pain and numbness in the leg or foot.

The tingling typically occurs in the lower legs. Additional symptoms may involve discomfort, a feeling of tightness, and inflammation in the affected limb.

Fix It

CECS is expected to occur shortly after you begin physical activity and may become more severe throughout your workout. Initially, the symptoms tend to subside once you cease exercising. However, if the condition worsens, the symptoms could persist for several days. In such instances, it is advisable to stop exercising and consult a healthcare professional.

8. Entrapment Syndrome

A tingling feeling occurs due to blood that is stuck in the popliteal artery, located behind your knee. When the artery is compressed, less blood reaches your lower leg. This can cause a tingling sensation along with occasional feelings of weight or discomfort.

Fix It

Continuously bending your legs while running may lead to the artery being compressed in your calf muscle. Typically, ceasing running alleviates the pressure on the artery, although in certain situations, surgical intervention is necessary to release the artery and restore blood flow.

When to Consult a Physician Regarding Persistent Numbness Following Physical Activity

Usually, leg tingling following physical activity is harmless and typically goes away within a few minutes of resting, according to Chukumerije. The primary reason for leg tingling is muscles that have lost nutrients because of dehydration and/or an imbalance in electrolytes.

If the tingling is slight and doesn’t bother you, it’s okay to continue with your daily activities. As the blood is no longer required for intense physical activity, some of the blood flow will leave your muscles, and the tingling sensation may disappear.

If your tingling persists for a reasonable period, such as an hour or more after you finish exercising, think about recording it in a workout log. Document when you first noticed the tingling: Does it occur after you’ve been working out for several minutes, or only after you’ve stopped?

Note the exact location where you are experiencing the sensation. For example, new running shoes can press against nerves on the top of your foot, causing a tingling feeling in your legs after walking if they are tied too snugly. Tingling in muscles following exercise that extends down the back of your thighs might suggest issues with your lower back.

Your notes could be useful in identifying the cause, especially if your tingling occurs occasionally. Are you wearing any specific clothing that might be restricting blood flow or pressing against a nerve? Do you experience any pain in your body at the same time, even if you’re not sure if it’s connected?

Keeping detailed notes can assist you in discussing your symptoms with your physician and obtaining a correct diagnosis if the feeling starts occurring regularly during your workouts.

Early detection and intervention can assist in preserving limbs and lives, according to Chukumerije.

The Takeaway

• Muscles grow larger while working out to handle the higher blood circulation. This might put pressure on nerves and blood vessels, leading to a tingling sensation in the legs.
• Additional causes may involve a histamine reaction, insufficient electrolytes, and spinal problems.
• Numbness in the legs following physical activity is usually nothing to worry about, but if it persists for more than an hour or starts occurring regularly during your workouts, it’s advisable to consult a physician.
