I am having pain above right knee from past three months, I consulted doctor for the same. She told it is early stages of osteoarthritis. I took three days ultrasound therapy for knee. Even though , the pain was reduced only 40 percent. Before starting the pain, I had fell down 8 months back. But the pain went way within week. I am not understanding whether it is due to osteoarthritis or due to injury, when I fell down. Please suggest me any home remedies or other suggestions. I am very disturbed and depressed with this pain. Is it anything serious.
