Reactive Arthritis

Posted on March 4, 2026 by Patrick Hercules

Reactive arthritis is a condition that occurs when the immune system reacts to an infection somewhere in the body and causes joint pain and inflammation. This infection usually starts in the digestive system, genitals, or urinary tract. Reactive arthritis usually affects the knees, ankles, and feet, but it can also cause inflammation in the eyes, skin, and urethra. Reactive arthritis is considered a form of a group of inflammatory diseases that mainly affect the spine, joints, and places where tendons and ligaments attach to bones called spondyloarthritis (SpA).

Although reactive arthritis isn’t contagious, the bacteria that cause it can spread through sex or food. Several types of bacteria can trigger reactive arthritis, including:

Chlamydia trachomatis

Clostridium difficile (C. Difficile)

Escherichia coli (E. Coli)

Campylobacter

Salmonella

Shigella

Yersinia

While only a small number of people who are exposed to these bacteria develop reactive arthritis, certain factors increase the risk of developing the condition, including:

Infection

Sex assigned at birth

Genetics

The symptoms of reactive arthritis usually start one to four weeks after a triggering infection. Common symptoms include:

Pain and stiffness

Urinary issues

Swollen toes or fingers

Eye inflammation

Inflammation of tendons and ligaments where they attach to bone

Skin issues

Lower back pain

Reactive arthritis isn’t common and usually happens for a short period of time. For most people who experience this condition, symptoms can come and go, usually disappearing within a year.

A healthcare provider can diagnose reactive arthritis with a physical exam, as they check the eyes and joints for inflammation, warmth, and tenderness, as well as the skin for rashes. They may also order blood tests, joint fluid tests, and imaging tests to help diagnose the condition.

The main goals of treatment for reactive arthritis are to relieve symptoms and treat any infection that may still be present. Since reactive arthritis can affect different parts of the body, there may need to be multiple doctors or healthcare providers involved in treating this condition. Treatments for reactive arthritis can include:

Medicines such as nonsteroidal anti-inflammatory drugs (NSAIDs), steroids, and rheumatoid arthritis medicines

Physical therapy exercises that strengthen the muscles around the affected joints, improve flexibility, and prevent stiffness

Although genetics is a risk factor for developing reactive arthritis, that risk can be lowered by reducing exposure to bacteria that cause infections by:

Practicing food safety

Preventing sexually transmitted infections

Carpal Tunnel Syndrome

Posted on May 8, 2025 by Patrick Hercules

Carpal tunnel syndrome is one of the most common hand conditions. It is caused by extra pressure on the median nerve in the wrist’s carpal tunnel.

Symptoms of carpal tunnel syndrome usually start gradually and can include:

Tingling and numbness in the wrist, hand, or fingers
Weakness
Pain in the wrist, hand, or fingers
Trouble using hands to hold or control objects

Several factors have been linked to the risk of carpal tunnel syndrome. Although they may not directly cause carpal tunnel, they may increase the risk of irritation or damage to the median nerve. These include:

Anatomical factors
Sex assigned at birth
Nerve-damaging conditions
Inflammatory conditions
Medicines
Obesity
Body fluid changes
Other medical conditions
Workplace factors

To diagnose carpal tunnel syndrome, a healthcare provider will ask questions about your symptoms and perform a physical exam and other tests that include:

Tinel’s sign
Phalen’s test
X-ray
MRI
Ultrasound
Electromyography
A nerve conduction study

Healthcare providers treat carpal tunnel syndrome with nonsurgical treatments first. The most common carpal tunnel treatments include:

Modifying your daily routine
Supporting and strengthening your wrist
Taking over-the-counter medication
Wearing a splint (especially at night)
Physical therapy
Changing your posture or working environment
Corticosteroids

You may need carpal tunnel surgery if nonsurgical treatments don’t relieve symptoms. The goal of carpal tunnel surgery is to relieve pressure by cutting the ligament pressing on the median nerve. The three different techniques used in carpal tunnel surgery include:

Endoscopic surgery
Open surgery
Ultrasound-guided surgery

It is best to treat carpal tunnel syndrome as early as possible after symptoms start. There are simple things that you can do for yourself that may help symptoms go away, such as:

Taking more frequent breaks to rest the hands
Not doing activities that make symptoms worse
Using cold packs to reduce swelling

If you have any questions or concerns about carpal tunnel syndrome or carpal tunnel surgery, you can receive more detailed information from a doctor at Orthopedic Specialists of New York, located on Jamaica Hospital Medical Center’s campus. To schedule an appointment, please call (718) 206-6923.

National School Backpack Awareness Day

Posted on September 13, 2017 by Joann Ariola

Backpacks are essential back-to- school items for kids. They come in different colors, sizes and shapes and most importantly they help children to carry their belongings. Backpacks are preferred by many in comparison to shoulder bags because when worn correctly, they evenly distribute weight across the body. However, if worn incorrectly they can cause back pain or injuries and eventually lead to poor posture.

To prevent problems associated with improper backpack use, parents should first purchase a backpack that has the following features:

Lightweight
Wide and padded straps
Multiple compartments
Padded back
Waist belt
Correct size (A backpack should never be wider or longer than your child’s torso).

Practicing these safety tips will further reduce the chance of back pain or injuries caused by backpacks:

When packing, heavier items should be placed to the back and center of the backpack. Lighter items should be in front. Sharp objects such as scissors or pencils should be kept away from your child’s back. Utilizing different compartments can help in distributing weight.
Do not over pack. Doctors recommend that children should not carry backpacks that weigh more than 10-15% of their body weight.
Ensure that children use both straps. Using a single strap can cause muscle strain.
Adjust the straps so that the backpack fits closely to your child’s back and sits two inches above the waist. This ensures comfort and proper weight distribution.
Encourage children to use their lockers or desks throughout the day to drop off heavy books.

The Pediatric Orthopedic Society of North America recommends that parents should always look for warning signs that indicate backpacks may be too heavy. If your child struggles to put on and take off the backpack, they are complaining of numbness or tingling or if there are red strap marks on their shoulders -It may be time for you to lighten their load.

Plantar Fasciitis

Posted on August 17, 2017 by Andrew Rubin

Have you ever experienced heel pain when you take those first few steps in the morning? The cause of this discomfort may be due to a tightening of the band of tissue known as the plantar fascia that runs along the bottom of the foot, from the heel to the toes.

When this ligament becomes strained, irritated, inflamed or swollen and causes pain when walking, the condition is known as plantar fasciitis.

Risk factors and causes of plantar fasciitis:

•High foot arches
•Flat feet
•Standing or walking on a hard surface for long periods of time
•Being overweight or obese
•Poor fitting shoes
•Tight Achilles tendons or calf muscles
•Tiny tears in the plantar fascia caused by repetitive straining
A proper diagnosis of plantar fasciitis is made by a physical examination of the foot and obtaining a comprehensive medical history of the patient. An x-ray or an MRI may be needed to see if there is a bone fracture that is causing the problem, also to determine if there is a bone spur present on the bottom of the heel.

Treatment of plantar fasciitis can involve taking an anti-inflammatory medication, physical therapy, stretching exercises, shoe inserts known as orthotics, steroid injections, and ultrasound. In severe cases, a surgical procedure may be necessary to provide relief.

If you would like to schedule an appointment with a podiatrist at Jamaica Hospital to evaluate any foot conditions that may be causing discomfort, please call 718-206-6712.
