Chronic Lower Extremity Pain and Weather: What Can We Learn from the Cloud?
Now that winter has arrived, it is a good time to review the association between weather and chronic pain. Around 400 BC, the Greek physician Hippocrates wrote that certain weather patterns exacerbate joint pain. What does modern science say? Despite many studies over the past several decades, there is no definitive answer. Some studies found a biological effect of weather on certain types of chronic pain and other studies have been unable to demonstrate a definitive association. It is likely that a connection between weather and chronic pain exists, but the relationship is complex and highly variable. However, there is no dispute that many people with chronic pain believe that the weather impacts their pain. In this post, we explore self-reported weather sensitivity among individuals with chronic pain using the Quell Health Cloud®.
Weather Sensitivity Patterns in the Quell Health Cloud
As a starting point, how many Quell users report that weather impacts their chronic pain? We analyzed data from 7,700 Quell users with chronic lower extremity pain who uploaded their demographic (e.g., age, gender) and clinical (e.g., medical conditions, pain levels) data to the Quell Health Cloud to support pain research. In this group, 62% indicated that weather aggravates their chronic pain, 21% were not sure and 17% said that weather had no impact on their pain. Among the 62% that reported an influence of weather on their chronic pain, the most common triggers were rain/snow (81%), cold temperatures (79%) and humidity (38%). Other meteorological conditions such as hot temperatures, wind and cloudy conditions were less frequently noted.
Next we looked at the demographic and clinical factors that predict which Quell users are sensitive to weather. We used a statistical analysis technique called logistic regression. The list below shows the factors most closely associated with weather sensitivity.
- Age < 65 years
- Chronic pain at least 4 years
- Pain interferes with sleep
- Pain interferes with mood
- Shoulder pain
- Hand / wrist pain
- Prior leg / foot injury
- Headaches / migraine
We see that female Quell users who are not elderly (i.e., less than 65 years of age), have had chronic pain for at least 4 years and whose pain interferes with their sleep or mood are more likely to have weather sensitivity. Users with shoulder pain or hand/wrist pain in addition to their leg pain are also more susceptible. Finally, users that report having a prior leg injury, arthritis, fibromyalgia or headaches/migraine are more like likely to experience weather sensitivity than those without these conditions.*
Managing Weather Sensitivity
There are steps you can take to help manage your chronic pain if it is weather sensitive. The most important is increased awareness and planning. Try to pay close attention to the forecast and plan your upcoming activities appropriately. If the weather is of the type that usually increases your pain, then consider taking it easy and not pushing yourself.
Quell can also help. It can be used as often as needed, even 24-hours a day, to provide lower extremity pain relief when you are having a bad day due to weather. Moreover, the Quell Health Cloud will automatically track your local weather and alert you on days that are likely to have greater pain. The Quell mobile app will also suggest a therapy increase on those days that you can choose to accept.
The relationship between weather and chronic pain is complicated. Regardless, if your experience is that certain weather patterns aggravate your chronic pain, then the association is real and needs to be managed. An increased attention to the weather forecast and using Quell on those difficult days may help you get through the winter with less pain and disruption to your life.
