Thigh and groin pain

Causes of pain in the thigh and groin

Muscle injury groin
The muscle injury causes pain in the upper thigh and groin ; for example, may occur during a kick in a ball.

If the pain is in the upper and anterior, the affected muscle is the quadriceps.
In the case of pain inside the thigh and groin, the cause may be the injury of an adductor muscle.

Quadriceps Trait
The quadriceps is a group of muscles on the front of the thigh. The quadriceps extends (straightens) the knee.
In case of injury, the rupture of muscle fibers causes:

  • hematoma ,
  • Swelling,
  • Severe pain in the anterior thigh area.

The cause may be a kick in the ball or a sprint.
The injury usually occurs in the upper or lower part of the muscle, near the tendons, being rare in the middle of the thigh.
In the first two days the patient limps.
The symptoms are also felt when walking or with simple movements.

When acute inflammation passes (after 3 days) the pain occurs when the person does more difficult activities, such as running or climbing stairs.

The cruralgia or crural neuralgia is the inflammation of the crural or femoral nerve.
It can cause pain along the nerve, that is, in the lower back that stretches up to:

In this case, the pain increases during some movements of the back that stretch the nerve, in particular the extension (arching the spine back).

The hip osteoarthritis is a type of arthritis  caused by degeneration of the joint and is caused by aging.
Symptoms include chronic thigh pain.


Pain in front of the thigh


Wounds and traumas
The skin lesions and bruises on the thigh cause pain.
A fracture of the femur causes a lot of pain in the front of the thigh.
In the thigh a hematoma or ecchymosis is often formed  due to minor trauma, especially in women who have a worse circulation than men.
Generally, blood is absorbed in 2/3 weeks without treatment.

Quadriceps muscle injury
The quadriceps muscle tear also causes sudden and severe pain in the thigh.
Muscle injury occurs when the muscle lengthens excessively during a sports activity.

Osteomyelitis is a bone infection caused by bacteria.

Osteosarcoma is a cancer; the cancerous cells originate in the bone.

During pregnancy, changes that occur in the mother’s body can cause sore thighs.
The circulatory system needs to work harder during pregnancy because it increases blood volume, especially near the end of pregnancy.
Diseases such as edema (swelling) of the lower limbs and dysfunction of the pubic symphysis can cause pain during pregnancy .
Also, the larger dimensions of the uterus and weight gain during pregnancy can cause pain.
Excess body weight exerts pressure on the lower limbs.

Quadriceps Tendonitis
In case of overload or trauma, it is possible to develop a quadriceps tendinitis in the area above the knee.
Athletes suffering from this disorder are especially cyclists who regulate the bicycle saddle in a very low position.


Pain behind the thigh

Damage to the biceps femoris
One of the most common muscle injuries is the distension of the femoral biceps. The individual feels pain in the back of the thigh.
The femoral biceps is a muscular structure of the leg that starts from the gluteus (ischium) and ends behind the knee.

The injury is caused by a tear  or rapid movement .
Climbing can damage the biceps femoris.
Distension also causes difficulties in stretching the leg.

The ischio-crural
group consists of the posterior muscles of the thigh:

1. Femoral
biceps , 2. Semitendinal,
3. Semimembranacal or semimembranous.

Sprinters and jumpers are the most predisposed athletes to develop tendinitis .
The pain is felt in the back and lower thigh, in the area corresponding to the affected tendons.

The sciatica ( inflammation of sciatic nerve ) is another common cause of pain.

Piriformis syndrome
The piriformis is near the sciatic nerve. It is located below the buttock muscles, originates from the S2-S3 vertebrae and is inserted into the greater trochanter of the femur.
Overloading this muscle can cause pain.
Since it is located near the sciatic nerve, it can irritate or compress the nerve .

Muscle pain due to pyriform syndrome can be felt in the outer posterior part of the left thigh to the knee, being extremely rare in the right thigh.

Compartment syndrome
The compartment syndrome is a medical condition that occurs when pressure within the muscles increases excessively.
This can compress the nerves, blood vessels and muscles.

This pressure can reduce blood flow, preventing oxygen and nutrients from reaching the cells :

  • Nervous,
  • Muscular

Lack of oxygen causes tissue death.

Pain referred
When pain occurs in distant areas of the injury it is referred pain.
Often pain is caused by inflammation of muscles, ligaments or tendons of the hip or sacroiliac joint, but causes pain along the thigh.

Poor blood circulation
A person may feel pain in the thigh when he / she is sitting for a long time.
The pain is caused by poor blood circulation .
People who suffer from venous insufficiency, deep vein thrombosis (formation of a clot in a deep vein), and blood clotting problems may experience pain in the thighs and calves .

Painful Cellulite
Women who suffer from advanced cellulitis, severe fluid retention and frequent bruising may experience pain in the thigh.


What to do? Natural Remedies for Thigh Pain

Below are some of the home treatments for pain relief.

Moderate physical activity may be helpful in regaining full motion and eliminating lactic acid .
It is recommended to ride a bicycle or use the exercise bike because this activity does not overload muscles, tendons and joints.
It is possible to do stretching without stretching the muscle a lot.

Keeping your leg warm
Using woolen pants at night helps reduce pain in the thighs.
Keep the thigh rolled up in flannel : this is one of the most effective home remedies to relieve thigh pain.

The cryotherapy (cold therapy) is very useful to reduce pain.

  • Fill a plastic bag with several ice cubes and cold water.
  • Put it on your thigh for 20 minutes.
  • Repeat 2 – 3 times a day.

Massages : massage is recommended to get cramps through .
The massage should be performed towards the heart to promote blood circulation.
The therapeutic massage :

  • Improves local blood circulation,
  • Reduces muscle stiffness and warms muscles.

Massage the thighs with olive oil ; it is possible to add one or two cloves of garlic for best results.
