Painful & Hard Lump on Pelvis in Male or Female: Causes, Symptoms, Treatment

The pelvis is the area between the thighs and lower abdomen. It also is comprised of the bony pelvic area referred to as the pelvis. A number of organs such as the rectum, pelvic colon, bladder and genitals are located in this area. A lump can originate in any of these organs or in the bony part of the pelvis.

It can be quite challenging to identify the specific organ in which a lump is originating. The best approach is to check with your doctor for a more intensive diagnosis. This article discusses some of the common causes of lumps in the pelvis for both males and females.

Lump on pelvis male causes

Common lump on the pelvis in males causes include:

Inguinal hernia

This is a type of hernia that occurs in the lower abdomen near the groin area. Males are commonly affected. This is because a weak spot may be left behind after the testicles have descended. The intestines push through the weak spot to form a bulge known as an inguinal hernia.

Undescended testicles

Normally, males have two testicles hanging below the pelvic area. This is not the case during embryonic development. During this period, the testicles are located in the tummy, but descend before a baby is born. If one of the testicles fails to descend, it is usually felt as a small lump in the pelvis.

Lump in pelvis female causes

A lump in the pelvis for females can be caused by:

Uterine masses

The uterus is a common location to find masses and lumps. Ovarian cysts are most common. Some are fairly harmless while others can cause infertility or even displace the uterus.

Femoral hernia

A femoral hernia is a rare type of hernia. It is more common in females. This condition often causes a painful lump in the upper part of the inner thigh or groin.

Lump in pelvis in male and female causes

Other than the above causes, a pelvic lump in either male or female can be caused by a number of conditions. They include:

Lymph nodes

Lymph nodes in the pelvis are located in the upper part of the thigh near the groin under the skin. Normally, they feel like pea-sized, firm, but slightly movable lumps. Infections and diseases lead to swelling of lymph nodes. When swollen, lymph nodes can form a noticeable lump that feels painful to touch. Other places you can find large groupings of lymph nodes are the neck, armpit and under chin. For example, a pea-sized lump under chin no pain that is always there is actually a lymph node.

Incisional hernia

This is the most common type of hernia. It develops after a surgical operation or an injury. The typical characteristic of hernias is that they tend to disappear when you are lying down and enlarge when lifting heavy objects, coughing, crying or coughing. Most are not painful but some can cause discomfort or even pain.


Cysts are very common causes of lumps, both under the skin and inside body organs. A painful lump in the tailbone area can for example be caused by a pilonidal cyst. Large lumps in the uterus can be caused by ovarian cysts. Generally, cysts are slow-growing, harmless and often, but not always, painless. For example, a painful lump at base of skull left side can be caused by an infected epidermoid cyst.

Skin infections

Skin infections such as boils, inflamed hair follicles, and abscesses are quite common in the pelvis area. They are characterized by pus or fluid-filled bumps, most of which are painful. Serious infections also cause symptoms such as fever, swelling of lymph nodes, tenderness, warmth and skin redness.


Lipomas are slow-growing, noncancerous growths of fatty tissues that form soft and movable lumps under the skin. They are often painless but can cause some discomfort if very large.

Bone tumors

Bone tumors can be malignant or benign. Whatever the case, it is advisable to have them checked by a doctor. In any case, there is no way you can tell if a bone tumor is cancerous or not without medical diagnosis. The good news is that most are benign.


Hemangioma is a noncancerous but abnormal proliferation of blood vessels. It is most commonly occurs in lower extremities. Other than hemangiomas, varicose veins are another disorder of blood vessels that can cause lumps under the skin. Varicose veins develop in the lower legs. In the groin, the condition is referred to as saphena varix. It results in a lump that can reach the size of a golf ball which tends to disappear when lying down.

Skin tumors

Like bone tumors, skin tumors can be benign or malignant. Common benign tumors that can develop in the pelvis are warts. These are fleshy growths caused by HPV. They often, but not always, resemble a cauliflower.

Injury and trauma

Physical injury or trauma can cause a lump in the pelvis area. For example, sitting for a long time or falling on a hard surface can injure the tailbone. If blood vessels get damaged but the skin remains unbroken, blood may clot under the skin to form a lump. This is known as a hematoma. Hematoma leg lumps are very common. Injuries can also take the form of skin irritation or an allergic reaction. Lumps caused by most forms of injuries are usually painful and cause swelling.

Treatment for lump in pelvis male and female

Treatment options vary depending on a number of factors, mostly the cause of the lump. Your doctor will direct you on the best treatment procedure to follow after diagnosis.

The most important thing is to ensure that you go for medical diagnosis if you notice a lump whose cause you cannot explain. You are also not advised to rely solely on online information. For example, it has not been mentioned that inflammation of the aorta in the lower abdomen can cause a lump in the pelvis. You will find that a complete list of all possible causes of pelvic masses is quite a long one.

Other than lumps with unidentified causes, see your doctor if you notice signs of infection or diseases. Common ones include fever, swollen lymph nodes, pus formation, headaches and general weakness. Note that swelling of lymph nodes in more than one location is a sign of a serious infection or disease. For example, cancer in the lymphatic system causes signs such as lump in throat when swallowing, a lump in the groin and a swollen armpit all at the same time.

Self-diagnostic tools such as white lumps on tonsils pictures, causes and general online information are only meant to give you an idea of what you are to expect. They are advantageous in their own ways. In fact, it is advisable that you keep learning more about the possible health conditions and diseases that you can contract.
