I am experiencing extremly severe sudden headaches. I have s1 acute herniation, I have had prior l5 l4 laminectomy. I do have left sided cervical bulging discs at c4 c5. These headaches are debilitating, I have been to er 3 time and they did a full work up and found nothing, only the bulging discs. Is it possible that the headaches are coming from my lower back or neck. I have had 3 of these headaches in the last 5 days, they all occured while I was sitting, 2 were while I was driving the third was while I was having a bowel movement. Is any of this related to my back or neck? I have never had a problem with headaches. I am a 44 year old woman and i do have ddd as well. please any info you can give me would be great Please i need the help!!!!!!!
