Brief Answer:
Can be a disc related problem.

Detailed Answer:
Hello,
Thanks for posting your query.
It seems that due to excessive stress and exertion to which your back muscles are not used to, you have suffered a myofascial pain syndrome. There may be some spinal disc related problem involved which is causing you a persistent radiating pain to the leg.
You need to consult an orthopedician who after an examination will order tests like MRI of spine to find the extent of damage you have suffered.
The main treatment of such pain is bed rest along with pain killers and muscle relaxants. Muscle relaxants can help with your symptoms if used in appropriate dosage in combination with a potent analgesic.
You can get the appropriate drugs prescribed from your Orthopedician after examination.
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.
- Using an LS contour belt of appropriate size might be helpful in providing support to back muscles.
Also, maintain a proper posture while working, sitting and standing. Keep your back straight. If you work for long hours on the computer, the following link will tell you the posture to maintain while working:
