Back Contusion

A back contusion is a bruise of the deep tissues of the back. This occurs when one gets hit on the back forcibly. A 'black and blue' bruise can occur if small blood vessels under the skin tear or rupture from the injury. Because blood leaks out of the damaged blood vessels it causes a black-and-blue discoloration under the skin. If one gets hit in the back with enough force, a back contusion may develop. A contusion should not impede a person from walking, bending or moving. If a back injury impairs someone from walking, moving, bending or standing up then it is not likely only a back contusion and possible there is other trauma involved. Although most contusions are not emergencies, bruising on the back could signify a severe injury. People with back contusions should seek medical evaluation.

Back Pain NOS (not otherwise specified)

Based on this result it is not clear what could be the cause of the pain. The term 'not otherwise specified' is used in medicine when a clear cause for a certain condition cannot be determined. Please try specifying what type of pain or location of pain to obtain a more clear diagnosis.

Back Shingles (Herpes Zoster)

Shingles is a viral infection caused by varicella (the chickenpox virus). Once a person gets chickenpox, the virus remains in the nerve roots of the spine. The virus can become activated again after stress, or weakening of the immune system. When it re-emerges, often many years later, it can causes redness and painful lesions that look like pimples and blisters in the path of the affected nerve. The rash typically appears on only one side of the back. This rash is extremely painful and people may experience burning, searing and sharp pain before the rash appears and after it has already dissipated. This rash can be treated with an antiviral medication at the Doctor or Urgent Care.

Back sprain

A back sprain is an injury to the soft tissues (e.g., muscles, ligaments, tendons) in the back. Usually this is the result from extreme stretching of the muscles or ligaments in the back. It is also called back strain, pulled back, lumbar sprain, or lumbar strain, and occurs from sudden jerking of the back, such as in a fall, car accident or heavy lifting. A lot of the time the pain is mild in the beginning directly after the injury, and can gradually worsen over hours. Pain is often the worst the day following the injury occurred. Mild to moderate sprains often heal on their own in three to six weeks.

Bacterial Vaginosis (Vaginal Infection)

Inflammation and infection of the vagina resulting from overgrowth of one of several bacteria normally present in the vagina. Normally the vagina contains more good bacteria than harmful bacteria. When more harmful bacteria are present, then symptoms occur. The cause of bacterial vaginosis is unknown but several conditions increase the chance of acquiring it like new sexual partner, multiple sexual partners, and douching.

Baker's Cyst

A Baker's cyst is a fluid-filled pocket that forms behind the knee. People with this condition often feel a lump behind the knee. Another name for this condition is 'popliteal cyst'. This cyst forms from enlargement of the gastrocnemius-semimembranosus bursa. This condition is often seen in people with knee arthritis, meniscal tears or recent trauma. The pain from Baker's cysts often worsens from prolonged standing and activity. People often experience stiffness as well. If a bulge or lump can be felt behind the knee that may shrink after bending the knee, it could be a Baker's cyst.

Balanitis (Penis Swelling)

Balanitis is inflammation of the tip of the penis (glans) that is usually caused by poor hygiene in uncircumcised men. The inflammation can be due to infection, harsh soaps, or failure to properly rinse soap off while bathing. Several other diseases including uncontrolled diabetes can also cause balanitis. A specialist or urgent care can usually treat this problem.

Bartholin Abscess Or Cyst (Vaginal Cyst)

A Bartholin abscess is a build-up of pus that forms a lump (swelling) in one of the Bartholin's glands. These glands are located in the labia on each side of the vaginal opening and produce fluid used for lubrication during intercourse. This disorder occurs when one of the Bartholin glands become clogged. These glands may become clogged due to infection or injury and may not be noticeable at first. If the cyst becomes infected, the site of infection can be very painful and become enlarged.

Basilar Skull Fracture

A Basilar Skull Fracture is a fracture in the base of the skull that can cause black eyes, clear liquid (cerebrospinal fluid) to come out of the nose, blood to come out of the ear or severe scalp bruising. A CT scan of the head and a neurological examination by a physician is required. An ER visit is highly recommended. Symptify can help you find the nearest ER and give you the option to send your information to prepare them for your impending arrival.

Bell's Palsy

Bell's Palsy is the paralysis of one side of the face from inflammation of the facial nerve. The facial nerve is responsible for movement of the muscles in the face. It may become inflamed from a bacterial infection such as Lyme disease or a viral infection such as herpes, varicella, EBV or CMV. This usually happens in people between the ages of 15 and 60. The majority of patients will return to normal in 3 to 6 months. For some people, the weakness only improves minimally or persists for life.

Benign Paroxysmal Positional Vertigo

This is a disorder that causes a sudden sensation of the room spinning. Usually this occurs immediately after turning the head and moving. One may feel as if the room is spinning or experience the sensation of riding a merry-go-round. Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo. Symptoms increase with head movement and seem to get better when the eyes are closed and the head is kept still. This disorder is most common in patients over the age of 50. BPPV is associated with head trauma, or injury to the middle ear during surgery. About half the time the cause of this disorder is never determined. It is believed that this happens from a small microscopic stone that forms inside the semicircular canals of the inner ear. Inside the inner ear there are fluid-filled canals known as labyrinths that are responsible for perception of movement and balance. Within these labyrinths there are small otolith crystals that send the body information about it's place in space. If an otolith crystal becomes dislodged, it can send incorrect messages about the body's position and cause dizziness and vertigo.

Benign Prostatic Hyperplasia (BPH)

Benign Prostatic Hyperplasia (BPH) is caused when the prostate gland becomes enlarged. The prostate surrounds the urethra and is located in the pelvis. The urethra is a tube that empties the urine from the bladder to the penis. As the prostate becomes larger, it compresses the urethra making urination difficult. BPH can be a normal part of becoming older, although some men experience more symptoms than others.
