Hi I did review your concern Lumbar disc herniation causes back ache and sudden pain shooting from back towards the back of legs sometimes till the heels and toes. It is due to irritation of nerves caused by prolapsed lumbar disk. Accoding to my valued peer Dr,narender saini sir s suggestion-Herniation of disc has various magnitude, if its a small herniation than that will not put any pressure on the root or cord, and thus will not be symptomatic, this is usually present in many of us, but if the herniation increases and start compressing the cord, backache develops, and if it compresses the root, radiating pain in the leg develops. Your pain if does not goes away with acetaminophan hydrocodone you need higher pain meds under doctor guidance like naproxen, opiod analgesia and so on. Also to confirm diagnosis a MRI is needed if not yet done. You need to take rest for sometime time and lie in position that gives you least pain. after 3 weeks you can consult a physiotherapist to begin some physical exercise to strenghten your back muscles. I hope this helps Wish you all the best. Thank you for using healthcare magic.
