I am 5 weeks out from Alif on my l5s1 and will get sharp pains that start in the lower left back and go to my left side of groin. This stops me in my tracks. Has any one had this before? I called the doctor and they just said probably normal and we can talk about it next week at my 6 week appointment. It starting to scare me I have had it for about two weeks now. Help please!
