Hi @rstern99. Hope Im understanding your question as my vision/pem worse today🙃 The sleep study allowed healthcare providers to have clinical data that backed up my experiences such as oxygen level markedly lower. This allowed for Cpap to be prescribed which gives continuous oxygen and in turn this helps our entire body from blood cell level including hopefully the area causing your vibrations. I also do box breathing to reset my nervous system and finally am at point I can stretch my arms overhead when first wake up which seems to help. All of us are different but hope can glean some positives from this!🌈
