Love you all. I will update my status soon after taking doctor's advice.
Thank you so much
As geminigirl stated, you have classical symptoms of sciaticia.
An MRI of the Lumbar region L1-L5 is appropriate. Not a CT.
It is unlikely you have cancer.
It sounds like it could either be a bulging disk/pinched nerve in your back or even sciatica pain. You probably need some xrays and perhaps a CT or MRI scan to determine the actual cause.
Meanwhile, you can try heat or ice applied to the area that hurts the most and see if ithelps along with the medication that your doctor has given you.
I hope you get some relief soon.
When I stretch it pains. But not all the times, Its becoming worse, Some times I dont feel pain in lower back but pain continues in to thighs and legs. I am worrying if that could be something dangerous. Doctor giving me, PAN 40, TAXIM o 200, Metrozyl, Voltafom and Zincovit tabs. It doesnt pain in nights but pains with physical activity. Some times its paining up to back bone..
It sounds similar to what I have experienced except mine is in the right side. My problem has been diagnosed as a bulge disc pinching the sciatic nerve, hence the pain going down the leg and to the toes. I have been taking medication to calm the nerve and doing physical therapy. I have been dealing with this for over 3 months now. if you sit down and lift your leg toward straight out, does it hurt more? like it is stretching throughout your buttock and leg? don't do it to create more pain, though.
