Recently diagnosed with hoshimotos disease. On levothyroxin. Current persistent symptoms are some mild join pain (less than before recent thyroid diagnosed), still very tired, lower back pain that effects walking and standing, head ache at the back of the head that feels like blood is suddenly filling my skull to the point it might explode, occasional blurred vision in left eye, pins and needles in hands and feet especially big toes...,is there something more going on with me. I also have occasional muscle tightness and pain. Any ideas and what all this might add up to?
