So im 19 weeks pregnant and ive got SEVERE low back pain like on my right side. I know back pain is common but this is something else every step im taking i feel it. I cant even walk. It kills. When i cough it hurts. My right shoulder is also aching a bit Im worried. I have a hip condition on my left side but this is my right side? And also ive had a constant headache on my left side near my eye jts quite severe i went docs and they said its common.. Any advice??
