Hi, I have lower back pain and trying to pinpoint what is causing it. My bed was old, so I just bought a new one and now sleeping is better. I work as a preschool teacher and am bending all the time, though I ve been doing this for years. I started using the Nicoderm patch 2 weeks ago and have been placing on my upper buttox because I hear it is best to be at a meatier part of your body. Would that be it? I am 35F. Also, I recently stopped using the NuvaRing about a month ago. My breasts were super sore for 2-3 weeks but alleviated after I started my next period. Do any of these things sound more of a reason than the other for my lower back pain?
