Hello, Do you mean to say that her condition commenced after SHE was delivered to her mother. OR after she DELIVERED a child? She may be suffering from back pain preventing her from sitting and so she could be evaluated for a condition of sciatica or disk bulging that could cause the problem. Jerky movements should be evaluated by a neurologist specializing in movement disorders and could be related to after effects of anaesthetics used (if the delivery was recent) or it could be something entirely coincidental in terms of De Novo movement disorder. The other issues you mention of the various intolerances to environmental stressors sounds like something that is likely being caused by an inordinate amount of stress upon her. She may find relief by consulting with someone who can talk to her about what sorts of things are going on in her life including recently giving birth (i.e. postpartum depression) and perhaps some mode of either cognitive behavioural therapy or relaxation therapy with breathing techniques to slow down metabolism, visual imagery, and so forth would be helpful to her. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Dariush Saghafi, Neurologist
