Lateral epicondylitis, commonly known as tennis elbow, is a condition involving the tendons that connect the forearm muscles to the outer part of the elbow. This injury is typically caused by repetitive wrist extension and gripping motions, leading to irritation and pain in the tendon tissue near the bony prominence on the outside of the elbow. Topical pain relief creams offer a non-invasive, localized approach to managing the discomfort associated with this condition. This article explores the most effective ingredients in these creams and how to use them safely to find relief.
Identifying the Most Effective Ingredients
The most effective topical agent for tennis elbow is generally considered to be a Nonsteroidal Anti-inflammatory Drug (NSAID) delivered in a gel or cream format. Diclofenac is the gold standard within this category, available in both prescription and over-the-counter strengths. This localized application allows the medication to target the affected tendons with minimal absorption into the bloodstream, avoiding the gastrointestinal side effects common with oral NSAIDs.
Another widely used category is counterirritants, which include ingredients such as menthol, camphor, and methyl salicylate. These agents work by creating sensations of hot or cold on the skin, which distract the nervous system from the deeper pain signal originating in the elbow tendon. While they do not address the underlying inflammation, they can provide effective short-term pain relief and are often used for managing acute flare-ups.
For those seeking gentler options, natural or herbal compounds like arnica or topical Cannabidiol (CBD) may be used. Arnica and CBD are sometimes used for their potential anti-inflammatory and analgesic effects, though scientific evidence supporting their use for tennis elbow is less robust than for topical NSAIDs. These alternatives may suit individuals who have sensitivities to stronger pharmaceutical ingredients or who prefer a more natural approach for mild discomfort.
Understanding How Topical Relief Works
The mechanism of action for topical NSAIDs like diclofenac is to inhibit cyclooxygenase enzymes, which are responsible for the production of prostaglandins. Prostaglandins are lipid compounds that mediate inflammation and pain signaling in the body. By applying the NSAID gel directly to the skin over the affected area, the active ingredient is able to penetrate the skin layers and directly inhibit these enzymes in the underlying inflamed tissue.
Counterirritants utilize a different physiological pathway to manage pain. Ingredients such as menthol and camphor stimulate specific nerve endings on the skin surface. Menthol activates the TRPM8 receptor, which is responsible for the sensation of cold, while camphor activates similar receptors to produce a warming sensation. These strong, localized sensations essentially override the pain signals being sent from the deeper, damaged tendon tissue to the brain.
Proper Application and Safety Precautions
Achieving maximum effectiveness from a pain relief cream depends heavily on proper application technique. The area of the elbow should be clean and dry before applying the cream to ensure optimal absorption of the active ingredients. A thin layer of the product should be gently massaged into the entire painful area until it is fully absorbed into the skin.
Follow the specific dosage and frequency instructions provided on the product label, especially for NSAID gels. Applying more than the recommended amount does not increase the benefit and may increase the risk of side effects, such as localized skin irritation. You should avoid applying any topical cream to broken, cut, or irritated skin to prevent adverse reactions or increased absorption.
Patients should be cautious about using topical NSAIDs if they are already taking oral NSAIDs, as this concurrent use can increase the total systemic exposure to the drug. Additionally, covering the application site with a non-breathable bandage or applying external heat should be avoided unless specifically directed by a healthcare professional.
Recognizing When Professional Help is Needed
Topical creams are typically a short-term solution for managing the pain associated with tennis elbow. If the pain does not show significant improvement after 7 to 14 days of consistent use and rest, it is time to consult a doctor or physical therapist. Prolonged discomfort may indicate a more severe condition or a different underlying issue that requires more comprehensive treatment.
Professional evaluation is also necessary if the pain becomes severe, significantly limits your ability to perform daily activities, or if you experience concerning symptoms such as numbness, tingling in the forearm or hand, or visible swelling and fever around the joint. While creams can provide temporary relief, they do not address the core issue of tendon breakdown, and a healthcare plan may involve physical therapy, bracing, or other targeted medical interventions.
