Thank you for your question, and thanks to Dr Dinesh for the very useful tips on back pain. There are potentially many causes of your lower back and/or hip pain.
It is important to differentiate the origin of the pain, and a thorough physical examination and history of the symptoms would be important.
Radiological imaging such as an MRI would be also useful in identifying the cause of the pain, and then we can start you on proper treatment. Many a times, medication and physiotherapy would suffice in alleviating the symptoms. Proper back care is important as well.
If the pain is persistent, it would be useful for you to consult a doctor, and then we can help toward working out the cause of the pain.
Hope this is useful.
