[|Human|] I have a severe needle like pain at the left side of my lower back. I visited a doctor recently and he suspects that there might be a cyst at the L4 L5 region. He has asked me to get an ultrasound done and an x-ray. What kind of a cyst can this be. I have been having this pain for about 4 years now. and never bothered. Only now as the pain increased, i thought i must visit a doctor. since then i am  extremely worried.
[|AI|]  Dear patient First according to me cyst is very rare condition and your symptoms do not justify that diagnosis. Also, ultrasound is not sufficient to diagnose l45 cyst. So I think possibility may be 1. Disc prolapse with nerve compression 2. Muscular pain.  So you need to be investigated with MRI of lumbosacral spine with screening of whole spine.  It gives detail of nerves, disc and bones. So visit radiology center nearby you and get it done.  Take expert spine surgeon opinion with report. Meanwhile, start tab attract one at bedtime and take tab regain plus vitamin B12 combination at bedtime for 10 days.
