Thigh pain right or left

The thigh pain can be caused by structures that concern:

  • bone (femur),
  • hip or knee joint,
  • muscles (quadriceps, hip flexors, adductors and tensor fasciae latae muscles),
  • nerves (sciatica, cruralis and cutaneus femoris lateralis),
  • Blood vessels
  • Tendons and connective tissue.

In addition, the pain can be perceived from other structures or organs of the body and radiate into the thigh.

The probability of thigh discomfort is the same on the right and left.


Causes of thigh pain

Cause of muscle strain

A strain of the quadriceps may occur after intense, vigorous physical activity, such as:

  • Sprint
  • Jump
  • Football match.

Symptoms appear on the front of the thigh.

Jumpers and high-speed skaters often suffer slight thigh strains.

If the pain does not pass within 2 days, the doctor should perform an ultrasound examination.

This investigation:

  • Is non-invasive,
  • Costs little,
  • Indicated to detect a crack or strain.

In the case of a muscle injury, the most appropriate therapy is Tecartherapy, an electrotherapy that favors:

  • The absorption of a bruise,
  • The regeneration of muscle tissue.

Tecartherapy works mainly in depth, in contrast to other physiotherapeutic devices.


Osteomyelitis is a bone infection.

The most affected bones are:

  • Femur
  • Humerus
  • Vertebra.

Other symptoms are listed below:

  • Fever
  • Swelling
  • overheating,
  • Reddening.


Degenerative arthritis is a disease of bones, joints, articular cartilage and subchondral bones (located under the cartilage layer).

This pathology causes:

  • Rigidity
  • knee swelling or effusion (accumulation of fluid in the joint) in the hip,
  • Circulatory.

The disease is caused by:

  • genetic factors,
  • Diabetes
  • Lesions
  • Overweight
  • Other factors.


Symptoms of sciatica include pain in the leg (thigh, calf, ankle and foot), loss of strength and sensitivity, and tingling.

This condition is characterized by inflammation of the sciatic nerve and may be caused by a herniated disc.

Cancer: The bone tumor forms in the bones of the arm, thigh, tibia and pelvis.

Cancer causes a dull pain along with swelling or redness of the skin.

Soft tissue ossification

These are bony formations inside a muscle, usually as a result of trauma.

Pain in the outer thigh

Pain on the outside of the thigh can be caused by:

  • A trauma,
  • A problem of the tensor fasciae latae muscle or its tendon,
  • A pain radiating to the muscles,
  • An inguinal tunnel syndrome.

Ileotibial bandell syndrome is a connective tissue overload disorder on the outside of the knee and thigh.

The ileotibial ligament is a structure that stabilizes the knee joints during:

  • the diffraction,
  • The stretching.

Ileotibial-bandell syndrome causes pain when walking as soon as the heel touches the ground.

The trigger points are points inside the muscle that cause local and distant pain once activated.

The triggers that can cause pain along the outer or lateral thigh area are:

  • Middle gluteal muscle,
  • Small gluteal muscle, the pain reaches down to the ankle and heel and can also cause tingling in the toes,
  • lateral width of the quadriceps,
  • Musculus tensor fasciae latae.

The muscle pain originating from the gluteal muscle and radiating into the lateral parts of the thigh is more common on the right.

Meralgia paraesthetica is a pathology that affects the nerves. The inguinal ligament narrows the lateral cutaneous femoral nerve.

This nerve is a sensory nervous structure that produces hot (burning) pain in the upper and outer areas of the thigh.

Pain inside the thigh

Pain inside the thigh can be caused by:

  • osteoarthritis of the hip joint,
  • pubic inflammation,
  • menstrual pain (on the days preceding menstruation, pain is felt from the abdomen to the thighs),
  • Muscular strain or stretching,
  • Muscle contracture of the adductors (usually after football training).

Severe thigh pain


Intense physical activity causes lesions on the muscles of the thigh. Some of the most common causes of pain include:

Meralgia paraesthetica

When the lateral cutaneous femoral nerve of the thigh is narrowed by an inguinal ligament, the person feels pinprick-like pain (severe burning) above and at the front of the thigh.


In the case of a herniated disc or disc hernia that constricts the sciatic nerve, the affected person feels a sharp pain in the thigh.

Symptoms worsen when the patient leans forward and often when he rises from sitting.

Muscle injury to the thigh

The abductors stabilize the knee.

The biceps femoris is a muscle that bends the knee. These muscles fatigue when the rhythm changes while running, such as a step extension or a sprint.

The risk of pulling one of these muscles is high.

Football players can get a muscle injury or a muscle strain of the adductors, which are located on the inside of the thigh.


With age, the cartilage in the joint joints degenerates and causes osteoarthritis.

Other causes of thigh pain:

  • Osteomyelitis
  • kidney stones, the pain may radiate to the gluteal muscle, groin and upper areas of the thigh,
  • Knee joint prosthesis.

Causes of thigh pain and tingling

Below are some causes that cause pain, numbness or tingling in the thigh.

  • neuropathy: metabolic disorders, nerve damage, poisoning, diabetes, etc.
  • nerve compressions,
  • Spinal disc herniation
  • Meralgia paraesthetica,
  • deep vein thrombosis,
  • Sciatica.

Causes of thigh pain when walking

  • strain of the quadriceps,
  • stretching of the flexor muscles or thigh flexors,
  • Osteomyelitis
  • Arthrosis
  • Meralgia paraesthetica.

Nocturnal thigh pain

The most common causes of nocturnal thigh pain are:

  • bursitis of the hip,
  • Circulatory
  • piriformis syndrome, causes pain when turning in bed,
  • Septic arthritis.

Thigh pain in children

Thigh pain in children has many causes:

  • Lesions
  • Bruises
  • Osteomyelitis
  • Osteosarcoma.

Legg-Calvé-Perthes syndrome or Perthes disease

This is a rare disease that occurs in children between 4 and 10 years of age.

The disease begins with pain in:

  • Hip
  • Groin
  • Thigh.

If the child grows, there is a difference in leg length and limited freedom of movement during abduction (spreading of a leg).
