Hi Janbo,
Thank you for your enquiry on behalf of your friend.
For swelling and pain we generally recommend our ColdCure range of products - as cold is a natural pain reliever and will also reduce inflammation and swelling.
We tend to promote 'charging' our ColdCure gels in the freezer, however, they can also be used from the fridge. The difference is that iced gels should be worn over a thin layer of fabric for a maximum of 20 minutes at a time, whereas refrigerated gels can be worn in direct contact with the skin and don't have a time limit (they can be used for as long as desired).
This being said, some Rheumatoid Arthritis and Arthritis sufferers don't tolerate the application of cold or ice.
We also have a BFST (Blood Flow Stimulation Therapy) range of wraps. BFST treatments are designed to improve blood flow in and around the targeted area. We generally advertise these wraps for injuries, however, people suffering from Rheumatoid Arthritis and other forms of Arthritis have experienced pain and symptom relief through the improvement of blood flow and circulation.
We offer a 30 day money back guarantee, therefore, your friend may want to consider purchasing both of our Elbow products to see which option works best for them.
More information about the BFST and ColdCure technologies, as well as Elbow Wrap design and pricing can be seen via the attached link :
