There are lots of things that you can do to help with your symptoms:
Taking pain relief regularly – either prescribed by your GP or from your local pharmacist
Keeping active – there are a lot of false beliefs that exercise will wear out the joint more, but keeping active will increase muscle strength, blood flow and joint lubrication
Using ice on a swollen joint for 15-20 minutes, regularly throughout the day
Using heat on a stiff, aching joint for 15-20 minutes, regularly throughout the day
Modifying activities that aggravate your sore joint (e.g. using your other hand, adjusting your exercise routine, moving items to lower shelves)
Adjust your desk and driving position to place the joints of the lower limb in a better posture
Self-massage of tight or aching muscles around the joint
Use of braces, supports or taping techniques
Stress-management techniques
Seek physiotherapy or osteopathy advice for specific exercise prescription and rehabilitation, along with other manual therapy techniques
Try holistic therapies such as acupuncture
