Hi backpaindrama and welcome to ehealth: This sounds like Sciatica...I, too, was made aware of this problem about two months ago...I found that when this happens the best thing to do is to lay flat on my back and rest it....From what I understand this is all from a disc in your back that has been damaged....When it hits you, it hurts so much that I swear it could bring a grown man to his knees...It's rough
There are physicians who treat this, but I would recommend only a Orthopedist who deals with Back problems.....I wish you well...Take care...
