Brief Answer:
Spondylottic changes in spine likely.

Detailed Answer:
Hello,
Thanks for posting your query.
Aches starting from the back and hip and radiating down the leg is due to a problem with the back (spine).

The most common cause is a disc prolapse. The ache radiates down to your calf if the protruding disc is compressing the nerves supplying your leg.
A disc prolapse can be caused following trauma to your back or, most of the times, due to aging.

The treatment:
An MRI scan will help in confirmation of the diagnosis.
In my opinion, you can wait for a while if the symptoms aren't getting worse.
Signs of worsening of symptoms are- pain causing disability, numbness, weakness, loss of urinary or bowel control.

When the symptoms get worse, kindly visit an Orthopedician or a Spine surgeon.

Meanwhile you can follow these measures:
- If the pain is severe, you need bed rest till the pain resolves.
- Get some analgesics prescribed and apply analgesic spray or ointments.
- While resting, keep a pillow under your knees if it doesn't bother you.
- Avoid lifting heavy objects.
- back strengthening exercises and stretching exercises for your hamstrings daily as advised by a Physiotherapist.
- avoid exercises in times of pain.
- improvise your posture while sitting.
I hope this answers your query.
