A learning disability is a general term that describes specific kinds of learning problems that cause a person to have difficulty acquiring certain skills. The skills most often affected are reading, writing, math, listening, speaking, and reasoning.
Osteopenia usually has no symptoms. There is no pain or any other sign to signal that the bone is becoming thinner, although there may be incidences of frequent fractures as the bones tend to become fragile and soft.
These symptoms are sometimes noticed before the symptoms of pain. Joint effusion of the knee is the most common symptom of osteoarthritis. There may be a formation of bunion at the toes which makes them red and swollen.
