i have been suffering from chronic pain from a large broad based left paracentral disk protrusion indenting the thecal sac and DDD. I have been experiencing sharp shooting pains on my left buttock and it goes along the whole backside of my thigh to my knee. Sometimes it get shooting pain to my growing area also. My question is what can be causing this? Would it be the disk protrusion or DDD. My other question is if I have DDD on my l5 s 1 and a disk protrusion on the same area should the disk protrusion cause less pain since it is dehydrated and has loss of disk height. I know this might be a stupid question to ask.
