Approximately 9 weeks after my first child, I began having difficulty getting up from chairs, taking stairs, carrying my newborn and having muscle weakness in the legs, hands, arms, and back. I've been evaluated for MS, MG, PD, Wilsons, Thyroid problems, electrolytes abnormalities, EMGs, Neuroassessments, etc. I'm at the Mayo clinic as I write and have been informed by the specialists that I do not have a neuromuscular disorder. I truly believe delivery contributed to the onset of the weakness. I was nearly incapacitated at the time (for about 6 months) but slowly regained some function. I currently function at about 75% of normal. What may have likely caused this?
