This is actually a question I get quite a bit. Often people are confused about whether or not they have sciatica or piriformis syndrome. As you ask Dr Google what is happening with you the symptoms for sciatica and piriformis syndrome seem almost identical. That's because they kind of are. Sciatica actually refers to the nerve that comes out of your low back and travels down to your toes, innervating almost everything in between - that is why claims of sciatica are so common.
