As per your symptoms there can be hip arthritis which can be degenerative or due to avascular necrosis of femoral head [AVN]. I will advise you do MRI of hip, and you can consult me with reports or with your doctor. Till time take analgesic and cartilage protecting medication like glucosamine sulfate. For hip arthritis joint flexion, extension and rotation exercises will help. Physiotherapist will help you better to learn more exercises in proper protocol.
