<s>[INST] Can a bulging disc in the L5 S1 area cause major pain, troubles with bowel movements numbness and tingly in my butt legs and feet? Also is this why I have allot of pressure and pain in my butt crack? I was also wondering if this can cause me to have issue with head aches? [/INST] Hi, I had gone through your question and understand your concerns.  If the bulging is compressing your lumbar spine and nerves, then it may cause your symptoms, especially if you have a narrow lumbar canal. You need to consult a Neurologist and if there is spinal stenosis you need decompressive surgery as the condition may progress. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. </s>
