In the middle of my pregnancy, 6-7 months ago, I developed some kind of tightness, stiffness and achiness in my neck. It started on the left side. I attributed it to the pregnancy weight gain and wrote it off even though its constant and annoying. There is no visible difference in my neck just by looking. But I gave birth 3 months ago and I have felt very unwell since then. My neck is still tight and achy but its on both sides now and I have also developed muscle pain/weakness, joint stiffness and pain and unsteadiness. My balance is off, I feel dizzy constantly. There is a pressure-like feeling in the base of my head and around my nose and forehead. I am shaky a lot. My vision is strange too and sometimes I have trouble concentrating and things seem surreal. I am getting really scared and anxious. My symptoms are severe enough to keep me from doing everyday things. I am miserable always. Please tell me if you have experienced this and what it could be. I am so scared.
