text: Degenerative conditions of the shoulder | Nuffield Health
  Cartlidge in the shoulder can wear down over time.
  Cartilage is the thin tissue that covers bone surfaces providing smooth, friction free movement. Wear and tear, injury or repetitive overhead movements like tennis can cause the cartilage in your shoulder to wear down (shoulder arthritis).
  Symptoms of degenerative conditions of the shoulder include:
  Pain, sometimes very severe
  A feeling of catching or grinding in the joint
  Taking over the counter pain killers like ibuprofen or paracetamol as well as resting and icing your shoulder may relieve your symptoms. Sometimes physiotherapy is needed to help you regain your range of motion and promote healing.
  Steroid injections may be prescribed to reduce pain and inflammation. In some cases surgery may be recommended.
