Osteoarthritis is a painful degenerative condition that can affect the knee joints. In its early stages, the symptoms may be mild and can normally be managed without surgery. However, as the condition develops, symptoms worsen and more invasive treatment options may become necessary, including surgery.
A sprained ankle can be a painful and debilitating injury. Depending on the severity of the sprain, you may be unable to put weight on the affected ankle and it may feel weak and unstable. You may have swelling, bruising and redness around the injury.
