my sister is suffering from multiple symptoms and no one has been able to help her. the problems start with her becoming extremely weak. she was barely able to get out of bed for three days, then on the fourth day she started to loose control of her muscles. her jaw and neck became "locked". she had to concentrate really hard to be able to talk or move. at this same time she has extreme stomach pain and she also becomes dizzy and her sight becomes very blurred. her heart rate elevated to 137 and blood pressure went up to 167/107. since the fourth day this has been happening spontaneously with no trigger factors. can you please help?
