So I herniated a disk in my neck back on February 21st. The doctor started me on prednisone, I took the whole prescription, then I had the cortisone shot. It helped with the severe pain however it came back to bite me in the butt. I was 2 weeks late for my period, then it started on march 12th, its the 31st of march today and it is constant. I am going through a super plus every 1-2 hrs, (spending a fortune on tampons, btw). I have fibroids and so I usually have a heavy, cramps period. But I've experience no cramps. I am usually very regular, but as almost everyone here has stated I too was not informed of the side effects off steroids. I read something about apple cider vinegar with water, think I'll give it a try, what do I got to lose. I'll let ya all know how it turns out.
