Hi, Noted the history of a very short memory loss, tiredness, less coordination, occasion pain in inner ear, throat and blurring of vision. All the symptoms put together the probable causes can be as follows: CNS that is central nervous system problems. Throat and ear is connected by Eustachian tubes and cause referred pain if there is any problem in throat. Any general disease like Typhoid can also cause similar varied symptoms. I would advise you the following in such a situation. Consult your Doctor fr preliminary evaluation, examination, investigations and primary treatment. Get a referral for a Specialist if required. Special investigations as per the clinical cause found. All these will help to know the exact cause so that a specific treatment can be done and effective. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. T. Chandrakant, ENT & General Surgeon
