A minor injury or a flare up of a previous problem, such as osteoarthritis, is very common in skiers. It is often possible to self manage such problems safely.
If in doubt seek advice in the resort.
Be particularly careful if skiing with an injury as it will greatly increase the risk of further injury. A particular risk is skiing with a swollen knee joint or minor ligament injury to the knee.
Minor soft tissue injuries can be treated by applying 'P.R.I.C.E' - the same techniques used to help manage more significant injuries. Although some people should not take anti-inflammatory medication, it can be very useful for those able to take it safely as it helps reduce pain and swelling. Check with the Pharmacist if you are unsure whether you can take this medication.
