I also feel that my whole left leg is pain when i press my heap at back. Could you advise me for further regarding the pain.. thanks.. [/INST] Hi Santa. This type of pain usually occurs due to a disc problem bat the lower back causing pressure on the nerves that go down to the foot. Another reason for such pain is the arthritis of the sacroiliac joint. To confirm the diagnosis one needs an MRI Of the lower back or LS Spine. Presently you could take a combination of diclofenac sodium 75 mg and thiocolchicoside 4 mg twice daily, after food. Show to a nearby doc (orthopedic or pain specialist) and start your further treatment </s>
