Muscle and joint pain do not only happen because of physical activities at the gym, or on the sports field. Sometimes simple everyday activities can cause injuries1. This can include anything from poor posture, carrying heavy bags or even neck strain from extended use of a computer,smartphone or tablet2. 

Heat rubs can generally be used up to 3 to 4 times a day


When it comes topical pain relief, the range of products to treat sore joints and muscles can seem overwhelming, with many types of creams, gels, rubs, and packs available3.

Here is some information on what to use when: 

Anti-inflammatory gel 

An anti-inflammatory gel can provide relief for strains and sprainsas well as muscle, tendon or ligament injuries4.  

Norflex Gels which contain benzydamine4, a non-steroidal anti-inflammatory drug (NSAID), work to reduce pain and inflammation in the body by reducing the production of hormone-like substances that promote the inflammatory response5. 

An anti-inflammatory gel can be applied directly to the skin over the painful, inflamed muscle or joint area, where it is then absorbed. This can provide pain relief for conditions such as torn ligaments or sprains; torn muscles or strains; sports injuries; inflammation of the fluid-filled sack around the joint (bursitis); inflammation of a tendon (tendonitis); muscle pain caused by an injury or infection (myalgia); bruising due to injury and even relief of joint pain and inflammation due to arthritis4. 

Recommended for use as a short-term treatment for the symptomatic relief of painful inflammatory conditions, topical anti-inflammatory treatments should not be used for longer than 10 days uninterrupted treatment without consulting your doctor4. 

Heat Rubs 

When it comes to minor pain, joint stiffness and muscle soreness, a heat rub can provide relief by warming and soothing the affected area6,7. Often containing menthol or methyl salicylate,  they work by causing the skin to feel cool and then warm, creating a temporary distraction from the pain point8. When using a heat rub, apply a thin layer to the affected area, rubbing it in gently and thoroughly. Heat rubs can generally be used up to 3 to 4 times a day8. 

Hot or cold packs 

Hot or cold packs, or a combination of the two, can provide relief for sore muscles and joints. Cold works by numbing sore areas and heat works by relaxing your muscles and dilating your blood vessels. This sends more oxygen and blood to the area. Much like a heat rub, a heat pack can also decrease the sensation of pain3. 

In addition to these types of treatments, an non-medicinal options are often also recommended. This includes initially making use of the R.I.C.E method. This acronym stands for Rest, Ice, Compression and Elevation9. 

New to the shelves at leading pharmacies is Norflex® Heat Rub, a topical treatment with methyl salicylateto reduce minor pain and stiffness6. Other products in this range include Norflex® Gel, a  topical triple acting anti-inflammatory gel for relief of strains and sprains, available over the counter without a prescription4. The range also recently launched Norflex® Gel Forte containing a higher concentration of the key ingredient Benzydamine Hydrochloride to provide extra-strength targeted relief10
