For last one year a peculiar thing is happening. In the morning my face is totally swollen up incl brain fog, totally confused, dont know what I am tailking, including the actions , focussing of eyes,difficulty & reluctancy in speaking , sort of tongue tied, now i HAVE BECOME CONSCIOUS ALSO, BECAUSE OF THIS ELSE I WAS AN ORATOR WHO CAN SPEAK FOR HOURS . Slight headache is always there, stiffness in and around mouth. all the possible test has been done to include MRI of brain ,spine, cardio test, eyes, ear, blood, urine. Nothing has been revealed. They are saying carotid artery stenosis but the doctor says it is not the real cause. I am a smoker. kindly help me with some medication URGENTLY. When I am lying down I am perfectly normal
