Weather and Arthritis: Is There Really a Connection?

Weather and Arthritis: Is There Really a Connection?

It’s long been conventional wisdom that weather makes arthritis pain worse.

The issue has been studied through the years, with conflicting findings. But three recent studies found weather does have some impact, said Dr. Robert Shmerling, writing for the Harvard Health Blog.

In one study with 222 participants who had arthritis of the hip, researchers from The Netherlands found that patients reported slightly worse pain and stiffness as barometric pressure and humidity rose, but the weather effect was small.

Another study looked at weather-related symptoms among 800 European adults with arthritis of the hip, knee or hands. They reported increasing pain and stiffness with higher humidity, especially in cold weather. In general, changes in weather didn’t affect their symptoms, though.

Participants of a third study reported their chronic pain symptoms. Most of the 2,600 individuals had some type of arthritis. This study found “modest relationships” between pain and higher humidity, lower atmospheric pressure and higher wind speed.

Past studies have looked at the impact of rain, humidity and rising or falling barometric pressure. Humidity, temperature, precipitation and barometric pressure may all be involved, Shmerling said.

“Having reviewed the studies, I find myself not knowing how to answer my patients who ask me why their symptoms reliably worsen when the weather is damp or rain is coming, or when some other weather event happens,” Shmerling said in a Harvard Health news release. “I usually tell them that, first, I believe there is a connection between weather and joint symptoms, and second, researchers have been unable to figure out just what matters most about the weather and arthritis symptoms or why there should be a connection.”

Whether it’s helpful to know the impact of weather is also not clear. The new studies will probably not have an impact on individual arthritis sufferers until weather or internal environments can be precisely controlled.

Still, identifying a link may help with understanding the causes and mechanisms of arthritis symptoms, which could lead to better treatments or preventive strategies, Shmerling said.

“In addition, figuring out why some people seem to feel worse in certain circumstances while others notice no change [or even feel better] in those same environments could help us understand subtle differences between types of arthritis or the ways individuals respond to them,” he said.

Experiencing Trigger Finger?

Experiencing Trigger Finger?

Can’t move your finger? It could be due to an orthopedic condition known as trigger finger. Learn more about the causes and treatments. 

We use our fingers so much in our daily lives — from typing to grasping objects to pointing and much more — that we often take these moveable joints for granted. But if your finger suddenly stiffens and you can’t accomplish your normal daily tasks, you’re sure to stop taking those joints for granted fast. What’s behind this stiffening? It’s most likely an orthopedic condition known as trigger finger.

Trigger finger can affect any finger, including the thumb, and may strike a single digit or multiple at once. Common trigger finger symptoms include general stiffness or a finger locking in a bent position. You may hear a clicking sound when you move your finger or feel soreness or a lump at the base of the finger. Treatment for trigger finger starts with conservative methods of rest and physical therapy. But first, let’s look at what causes trigger finger.

Trigger Finger Causes

Trigger finger, also known as stenosing tenosynovitis, or flexor tendonitis, is an inflammation of the sheath covering the tendon in the finger. The sheath allows the tendon to move freely. But when it’s irritated or inflamed, the finger stiffens and cannot straighten itself. Prolonged inflammation can also lead to scarring and bumps forming in the tendon, which further restricts the finger’s ability to move.

Similar to so many other orthopedic disorders, trigger finger develops as a result of repetitive motions. People who work at jobs requiring them to continually grasp or bend their fingers, such as musicians, tend to develop trigger finger in greater numbers. People who have diabetes, rheumatoid arthritis, or who have had carpal tunnel syndrome surgery before stand a greater chance of developing trigger finger. The condition also strikes more women than men.

Treating Trigger Finger: Home Remedies

Your orthopedist can diagnose trigger finger with a physical examination to feel for any areas of tenderness or swelling. During the examination you will also be asked to open and close your hand to pinpoint the center of the pain or see if your finger locks up.

Initial trigger finger treatments typically involve conservative methods, beginning with avoiding activities that cause the pain and stiffness. You may need to wear a splint to immobilize the finger and give the tendon time to heal. This period of rest could take between four to six weeks.

If your trigger finger is caused by an underlying chronic condition such as diabetes or rheumatoid arthritis (instead of just repetitive motions), treatment for those disorders can help relieve the symptoms of trigger finger.

Another treatment option to reduce pain and swelling is to take non-steroidal anti-inflammatory medications. A good home remedy for bringing down the swelling is to apply ice to the finger for 15 minutes three times a day is recommended. In some cases, your doctor may also prescribe a steroid injection into the affected finger.

Treating Trigger Finger: Physical Therapy and Surgery

One of the most effective ways to treat trigger finger is through physical therapy, which can effectively increase flexibility and strength in the finger and hand. Your physical therapist may also massage the finger gently to break up any scar tissue on the tendon, which can alleviate pain and improve your range of motion.

If conservative methods fail to restore mobility, surgery may be your next step. In a percutaneous release procedure, a needle inserted into the finger tendon loosens it so the finger can move smoothly again. This procedure is usually done on an outpatient basis. After surgery, you must keep the finger dry by covering it with plastic wrap when showering. You’ll wear a bandage for a few days. Once the bandage is removed, you should move your finger as much as possible to speed up the healing process.

It’s important to remember that surgery is only recommended when other conservative techniques are unsuccessful and your quality of life is significantly impaired by trigger finger. In most cases, trigger finger resolves without surgery and you can return to normal activities without pain or stiffness.
