This page features links to a selection of articles from authoritative sources, presenting diagnostic methods and treatment approaches for chronic, exercise-induced conditions. Some articles are designed for a layman audience, offering accessible insights, while others provide scholarly perspectives on emerging areas of consideration.
Popliteal Artery Entrapment

Diagnosing fPAES is challenging owing to a lack of standardized diagnostic testing and provocative maneuvers. Different maneuvers demonstrated varying diagnostic yields for fPAES. Exercise ABIs were the most reliable vascular laboratory test to detect changes attributable to fPAES and to distinguish it from chronic compartment syndrome.
PAES arises when the blood vessels in the area behind your knee (known as the popliteal fossa) are pressed or squeezed by nearby muscles or tissue. This article sheds light on the fact that this typically occurs due to a developmental irregularity where the artery and neighboring muscle tissues are not properly aligned, thereby causing pressure on the blood vessels.
Diagnosing PAES, a condition causing leg pain typically in young, healthy individuals, can be a challenge due to usually normal physical exam results; diagnosis involves ruling out other causes of leg pain through a series of tests including Ankle-brachial index (ABI) measurements, Duplex ultrasounds, Magnetic Resonance Angiography (MRA), CT angiography, and catheter-based angiography. The only effective treatment for PAES is surgery, which involves releasing the abnormal calf muscle and freeing the trapped artery, resulting in minimal impact on leg function and typically leading to a full recovery if diagnosed and treated early, though long-standing cases may require artery bypass surgery.
PAES is a rare vascular disease predominantly found in young athletes, causing calf and foot pain during exercise due to calf muscles compressing the popliteal artery and limiting blood flow to the lower leg. The condition can be effectively treated with surgery, which has a success rate of over 90%, though recovery may take four to six months; an alternative non-surgical treatment involves Botulinum toxin A injections, but these are less effective and only offer temporary relief.
In young, physically active individuals, claudication often results from conditions like CRECS and fPAES, which are frequently confused due to similar symptoms in the absence of apparent musculoskeletal injury or arterial venous disease. This study aims to differentiate between CRECS and FPAES by investigating their diagnostic testing, injury mechanisms, and distinct surgical treatments for successful outcomes.
Chronic Exertional Compartment Syndrome

Compartment syndrome, which often affects the lower leg among other areas, is a dangerous condition where pressure increases within muscle compartments, limiting blood, oxygen, and nutrient flow, potentially leading to serious damage or death. It has two forms: acute, typically caused by severe injury and a medical emergency that can cause permanent muscle damage, paralysis, or death without treatment, and chronic, usually related to intense exercise and not an immediate emergency, but can cause serious discomfort and disrupt normal activity.
Acute compartment syndrome (ACS) is a critical medical condition often triggered by elevated interstitial pressure within a sealed osseo-fascial compartment, which if left untreated for six hours, can cause irreversible ischaemic damage, long-term disability, or even fatality. Diagnosis is largely dependent on clinical observation, particularly noting a pain level that exceeds the apparent injury severity, and the initial treatment steps involve releasing any constriction and maintaining the limb at the level of the heart, with surgical decompression being the decisive treatment if symptoms continue.
Chronic exertional compartment syndrome is an exercise-induced condition causing pain, swelling, and possible disability in the affected muscles, primarily seen in young adult runners and athletes involved in high-impact repetitive activities. The symptoms, which include aching, burning, or cramping pain, tightness, numbness or tingling, and weakness in the affected limb, typically begin with exertion and diminish after stopping the activity, with nonsurgical treatments and activity modification usually effective, but surgery may be necessary if these interventions fail.
Compartment syndrome is a condition where pressure within muscle compartments becomes dangerously high, often due to injury or exertion. Acute cases, usually from severe trauma, can cause permanent muscle damage, while chronic cases, typically from repetitive activities, are generally reversible. Diagnosis involves pressure measurements and the treatment ranges from emergency surgery to lifestyle changes.
Stress Fracture

Stress fractures are small cracks or severe bruises in the bone that often happen to runners and athletes who participate in running-intensive sports, such as soccer. They can happen when someone exercises too much, changes their workout suddenly, or if their bones are weak, causing pain that gets worse when putting weight on the injured area, especially in the foot or lower leg bones.
Stress fractures are tiny breaks in a bone from too much use and they usually happen to athletes or workers who do a lot of physical activity. These injuries mostly affect bones in the lower body and cause pain that gets worse when you're active. Treatment usually involves rest, pain management, and sometimes immobilization or surgery, while prevention includes smart training practices, proper diet, and using the right equipment. Recovery can take up to two months.
Overuse or certain medical conditions can lead to tiny stress fractures in bones, especially in athletes who increase training intensity quickly. Yale Medicine provides a multidisciplinary approach to treatment, focusing on allowing fractures to heal with rest and alternate fitness routines, while also addressing underlying health conditions that could be contributing to bone fragility.
Shin Splints

Shin splints are often caused by overuse of leg muscles, especially in runners, dancers, or military recruits. They are typically treated with rest, ice, stretching, and supportive footwear. Prevention includes using appropriate athletic shoes, gradual training increases, and diversified workouts. If symptoms persist, medical consultation is necessary, as severe cases may need surgery or could signal other health issues.
Shin splints are a painful condition often caused by overuse, common in runners and people who engage in heavy physical activities. They are typically diagnosed through physical exams and treated with rest, exercises, medication, and proper footwear. Prevention includes using well-fitted shoes and gradually increasing exercise intensity.
Other exertion induced lower leg conditions
Additional information on several other conditions induced by exercise
Tendinopathy is a condition that causes pain and swelling in the tendons, typically resulting from injury or overuse, and can involve inflammation (tendinitis) or degeneration (tendinosis) of the tendon. Although the condition is common in athletes and those over 40, it can affect anyone, and its treatment may include rest, ice, strengthening exercises, stretching, massage, and sometimes surgery, with recovery times ranging from days to months.
Lower leg pain, which can feel like stabbing, burning, or cramping, can be caused by a variety of conditions including muscle, bone, blood vessel, and nerve issues. Due to the potential for serious complications, especially for those with underlying health conditions, professional medical advice is crucial for accurate diagnosis and treatment.
Peripheral arterial disease (PAD) is a condition where the blood vessels going to your arms and legs get narrow due to fat and cholesterol buildup, often leading to less blood flow, especially to your legs. Risk factors include smoking, getting older, and having diseases like diabetes, while symptoms can include leg pain and slow-healing sores; it's diagnosed through physical exams and imaging tests, and treated through lifestyle changes, medicines, and sometimes surgery.
Peripheral neuropathy is when the nerves that connect your brain to the rest of your body get damaged. This can lead to problems like weakness, numbness, and pain, and is often caused by things like diabetes, injuries, or certain treatments like chemotherapy.
