Im a bit (well, a lot) nervous right now. I have been experiencing a pinching/burning pain in the middle of my spine off to the left upper side today. Its getting worse tonight. Even when I lay down, I feel it. I have no idea what its from. Breastfeeding, maybe? Since I lean forward with no back support (I sit on my bed and feed him, unfortunately I dont have a nice comfy chair in my room and he's tethered to a monitor so its a pain to unhook him every time and go to another room) or could it be from the spinal I had a month and a half ago before my csection? Or, God forbid, a bacterial illness....like meningitis? 😨 Im freaking out (I have pretty severe health anxiety). Also, my arms feel weak and heavy. I hope its nothing serious 😧 I cant head to the ER because I refuse to bring the baby there with all the sick people, and he is breastfed....so theres that. Id be gone for hours. What should I do? What do you guys think it is?
