Can pins and needles or numbness come from bursitis or tendonitis? 

While bursitis and tendonitis are primarily conditions that affect the soft tissues, they can frequently cause secondary symptoms like pins and needles or numbness. These sensations, often described by patients in the United Kingdom as a tingling or a loss of feeling, usually occur when the inflammation in a bursa or tendon creates enough pressure to compress a nearby nerve. While the tendons and bursae themselves do not produce these sensations, their proximity to the body’s neural pathways means that significant swelling can have a direct impact on nerve function in the affected limb. 

What We’ll Discuss in This Article 

• The anatomical relationship between nerves, tendons, and bursae. 

• How localized swelling leads to nerve compression. 

• Common areas where inflammation causes tingling sensations. 

• Distinguishing between soft tissue pain and nerve related symptoms. 

• Clinical conditions like carpal tunnel that involve both tissues. 

• When numbness or pins and needles require urgent medical review. 

How inflammation leads to nerve compression 

Nerves often travel through narrow channels or tight spaces alongside tendons and bursae. When a tendon becomes thickened due to tendonitis or a bursa fills with excess fluid, the total amount of space in these channels decreases. This increased pressure can squeeze the nerve, interfering with its ability to send electrical signals correctly. This is known as nerve entrapment or compression. The resulting symptoms are not felt in the tendon itself but are instead projected along the path of the nerve, often leading to pins and needles or numbness further down the arm or leg. 

Common sites for nerve related symptoms 

Certain joints are more prone to this interaction because of their cramped anatomy. In the wrist, the tendons that move your fingers share a very tight space called the carpal tunnel with the median nerve. If these tendons become inflamed, they can easily compress the nerve, causing numbness in the thumb and first three fingers. Similarly, in the elbow, an inflamed bursa can put pressure on the ulnar nerve, leading to tingling in the small and ring fingers. In the hip, significant bursitis can occasionally irritate the nerves that travel down the outer thigh, causing a localized patch of numbness. 

Distinguishing between pain and tingling 

It is important to differentiate between the localized ache of a soft tissue injury and the radiating sensations of nerve involvement. Tendonitis and bursitis typically cause a deep, localized pain that is tender to the touch. Numbness and pins and needles, however, are specifically neurological symptoms. You might find that moving your joint in a certain way triggers a sharp jolt of pain (the tendon) followed by a wave of tingling in your hand or foot (the nerve). If the numbness is constant or if you notice a loss of muscle strength, it suggests that the nerve compression is more significant and requires professional assessment. 

Associated conditions in the UK 

There are several well known clinical conditions where soft tissue inflammation and nerve symptoms occur together. Carpal tunnel syndrome is the most frequent example, where the primary issue is often the swelling of the protective sheaths around the tendons. Another common issue is seen in the shoulder, where a combination of bursitis and tendonitis can lead to what is known as referred pain or tingling down the arm. According to NHS guidance on nerve compression, identifying the source of the pressure, whether it is a swollen bursa or a thickened tendon, is the first step in deciding the most effective treatment. 

Diagnostic approaches for neurological symptoms 

In a clinical setting, a GP or physiotherapist will perform specific tests to determine if your pins and needles are caused by local inflammation. They may tap on certain areas to see if it triggers a tingling sensation or move your joint into positions that purposely narrow the space around the nerve. If the cause is unclear, they may refer you for an ultrasound to visualize the degree of swelling in the bursa or tendon. NICE clinical standards suggest that in persistent cases, nerve conduction studies may be required to measure how well the electrical signals are traveling through the affected area. 

Managing inflammation to relieve nerve pressure 

The most effective way to resolve pins and needles caused by bursitis or tendonitis is to reduce the swelling that is causing the pressure. Following the PRICE method, protection, rest, ice, compression, and elevation, is the standard initial approach. As the fluid in the bursa is reabsorbed or the tendon thickness decreases, the pressure on the nerve should subside, and the normal sensation should return. It is also helpful to avoid positions that further compress the area, such as leaning on your elbows or sleeping with your wrists bent. Once the acute inflammation is gone, gentle stretching can help ensure the nerve can glide freely through the joint again. 

Conclusion 

Pins and needles or numbness can indeed be caused by the pressure from an inflamed bursa or tendon. While these neurological symptoms can be unsettling, they are usually a secondary effect of the localized swelling and often resolve once the primary inflammation is managed. However, because nerve compression can lead to long term issues if left untreated, it is important to monitor these sensations closely. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
