In ,y opinion i dont think you should worry , that is a kind of sciatica due to sitting alot on hard sufaces that causes pressure on your nerves coming from your spine it is common and increases with age and weight . avoiding lifting heavy object and spinal straightening excersizes and positions even while sitting and walking will be helpful . spinal nerve compression causes this kind of neuropathic pain due to disc herniation nerves going to your legs releived by relaxing , physiotherapy by your chirpractor , hot massaging your back twice daily with topical gels and even yoga , painkillers like advil ,muscle relaxants are recommended if no releive happened the i would suggest my patients for Xrays and CT for proper evaluation Please click THANK YOU and consider a 5 star rating with some positive feedback if the information was helpful.
